Liz Shaw, a brilliant scientist, joins UNIT to investigate the meteorites, and soon she and the Doctor are working together. A plastic factory, close to where the meteorites fell, has stopped production of dolls and now manufactures facsimile figures - a superior kind of waxwork, and window dummies. The owner, Hibbert, seems to be under the control of his new partner Channing. There are mysterious deaths in the area, and talk of strangely blank-faced figures in the woods. These are Autons - manlike plastic figures animated by the alien intelligence that came to earth in the meteorites. The factory displays some of its figures in a London waxworks. Dr Who in intrigued by how uncannily lifelike they are. Then he realizes that the key men in the administration of government are to be replaced by mobile facsimiles. The country, and then the world will be ruled by alien intelligence operating in human guise. Their role is to create chaos, and so pave the way for colonization by these emanations, the Nestenes, from another planet. The Doctor and Liz discover that the Autons are vulnerable - they can be rendered lifeless by the application of UHF waves at close quarters. The Doctor attacks this weakness, destroys the swarm leader and is able to end the invasion attempt. The Nestenes have been defeated, but there is always the possibility that they will try again.

(3b) THE SILURIANS - On Wenley Moor, a secret atomic research centre where a reactor converting nuclear energy to electrical power is being developed, work is being held up by inexplicable power losses and break-downs among staff. The Doctor traces the trouble to underground caves where prehistoric monsters live with a nest of highly intelligent man-like reptiles, the Silurians. They went into hibernation millions of years ago but have been resuscitated by accidental electric discharges from the research centre. They now claim back 'their' Earth. The Doctor strives for harmony between Man and Silurian. But then the rebellious and intolerant Young Silurian releases a terrible disease that will wipe out the Universe. The Doctor finds an antidote. The Silurians take over the research centre and plan to destroy the Van Allen Belt, which shields Earth from the Sun.

The scientist, a ruthless egomaniac, is at odds with Sir Keith Gold, executive director of the project, who urges a more cautious approach. Beneath his pose of interested observer, the Doctor is anxious to tap the nuclear power of the project as part of his plan to make the nuclear power of the project as part of his plan to make the grounded Tardis operational once more. His attempt to do this propels him into a parallel world, a Britain that is a republican dictatorship where he meets a very different Liz and Brigadier. in this world, too, Project Inferno is near completion as the penetration of the earth's crust unleashes primitive forces that will eventually destroy what the Doctor describes as a space-time continuum. First come the terrifying Primords - men who under the influence of the released Stahlman's gas have degenerated into a kind of primeval ape; then an immense volcanic eruption that destroys this planet. Before the final catastrophe, the Doctor manages to propel himself back into "our" world, where to his horror he finds that Project Inferno is nearing the final stage under the ruthless driving of Professor Stahlman. Desperately, the Doctor struggles to prevent a re-enactment of the catastrophe that destroyed the other earth. *Broken down by episode: Episode 1 - Using nuclear power, scientist drill through the earth's crust to release a new energy source.

The Doctor's suspicions of the visitors are confirmed when Jo tells him how she saw an Axon evolving out of the wall of the ship. He discovers that the vessel, the Axons, and the Axonite are all parts of one living creature, Axos; a parasite which will absorb all living energy on a planet, leaving a dead world.

(3l) THE SEA DEVILS - The master is now living in exile in a luxurious castle prison on a small island, governed by the loyal, but rather stupid, Colonel Trenchard. Doctor Who, who feels some sense of responsibility for his fellow Time Lord, decides to pay a visit. Jo goes along with him. When they reach the island, the Doctor is intrigued to learn that a number of ships have vanished mysteriously in the area. He insists on visiting a nearby Royal Navy base, where a strangely charred lifeboat, found after one of the wrecks, has been taken for investigation. The officer in charge of the top secret research base, Captain Hart, refuses to listen to the Doctor's theories, and so the latter insists on visiting a nearby fort which has been the scene of mysterious happenings. When they reach the building, which is being reconstructed so that it can be brought into use again, Jo and the Doctor are attacked by a Sea Devil, a strange man-like lizard of enormous size. The Doctor explains to Jo that the Sea Devil is a kind of relation to the Silurians, a race of intelligent lizards he once met in the mountain caves of Derbyshire. When Earth seemed likely to perish thousands of years before, they went into hibernation and left the planet to Man, who at the time was a kind of ape. Doctor Who thinks that the work at the fort has revived a colony of these creatures on the sea bed. It is becoming obvious that the Master has established some kind of power over Trenchard. While Jo and the Doctor are visiting Hart again to try to convince him of the existence of the Sea Devils, Trenchard smuggles the Master into the Naval Base where he steals top secret electronic equipment. With this, he is able to construct a calling device, and he summons a Sea Devil which almost destroys Jo and the Doctor. In the meantime, Hart has sent a submarine to investigate the sea bed near the fort. The vessel vanishes, captured by the Sea Devils. Jo and the Doctor escape from the Master's trap and manage to persuade Hart that something is wrong at the prison. they go together to investigate, but are too late. Sea Devils have raided the place, killing Trenchard and apparently capturing the Master. With the help of the Naval diving vessel, the Doctor manages to gain admittance to the Sea Devil's base where he finds the Master in a position of power; he plans to help the creatures to conquer the Earth and enslave humanity. The Doctor tries to persuade the chief Sea Devil to come to some peaceful settlement with the human race, and appears to be on the verge of success when his efforts are frustrated by the beginning of an all-out depth charge attack. This has been ordered by Walker, a ruthless politician who has been given responsibility for dealing with the crisis. During the attack, the Doctor manages to release the submarine crew and escape with them in their vessel. On their return to the naval base, Walker reluctantly agrees to allow the Doctor to make one final attempt to reach a peaceful settlement with the Sea Devils, but before the effort can be made the enemy, led by the Master, attack and capture the base. By using humans as hostages, the Master forces the Doctor to help him to build a machine which will revive Sea Devil Colonies all over the world. Jo manages to get out through a ventilator and releases the others. Captain Hart and his men recapture the base. The Master escapes and the Doctor goes in pursuit, only to be recaptured and find himself once more in the Sea Devils' base. He is forced to help with the construction of the machine, but once this is done, the Master's usefulness is at an end, and he and the Doctor are imprisoned together. Doctor Who then tells him that he has sabotaged the machine, and when switched on it will blow up the entire base, they must escape together or die together. They manage to reach the surface where they are picked up by a rescue helicopter. Apparently exhausted, the Master collapses, and is taken to an ambulance when they return to the naval base. But when the Doctor takes a look at the recumbent body on the stretcher, he finds a member of the helicopter's crew. Suddenly the helicopter takes off. The Master has escaped to fight another day.

(3m) THE CURSE OF PELADON - On the remote fringes of the galaxy is a primitive planet, ruled from a citadel on a mountain top by a king who bears its name - Peladon. Young King Peladon wants to improve life for his subjects, and so he has applied for admission to the Galactic Federation, a union of all the intelligent life forms in the Galaxy. A delegation has been sent by the Federation to assess Peladon's suitability for membership, and most of its members are already assembled. There are Arcturus, Alpha Centauri, and the Ice Warrior, Ixyr. Only the delegate from Earth has still to arrive. While the delegates wait, there is better disagreement between the King and his Chancellor, Torbis, on the one side and the High Priest Hepesh on the other. The Priest believes that contact with the worlds outside will ruin the Peladon they know. Soon afterwards Torbis is murdered, apparently by Aggedor, a semi-mythical monster, guardian of the planet's traditions. Doctor Who and Jo Grant enter the scene when the TARDIS makes an erratic landing near the Citadel; the Doctor is taken for the missing delegate from Earth and Jo for a royal princess. It soon becomes apparent that someone is trying to wreck the conference. Attempts are made to kill the Doctor Who and the other delegates and, accused falsely of sacrilege, Doctor Who has to do battle with the King's Champion.

(3n) THE MUTANTS - This new adventure takes the Doctor and Jo to an alien planet in the far distant future where they find new monsters - the Mutants, natives who have mutated into a strange and horrifying form. The action takes place on the Skybase from which earthmen rule the planet, on the misty poisonous surface of Solos, and in a network of underground caves where the Doctor finds the solution to the Solonians' desperate problems. Doctor Who and Jo are working in the laboratory when a mysterious object materializes in front of them. The Doctor knows that this is a dispatch box from the Time Lords, of a kind used only in dire emergencies. He must deliver it to the person or creature for whom it is intended, so he and Jo enter the TARDIS which dematerializes. They find themselves many hundreds of years in the future, on Skybase One, a giant space station in orbit round the planet Solos. A part of Earth's empire, Solos is about to be given independence. Jo and the Doctor meet the Marshal, the megalomaniac office in charge of the base and by virtue of this ruler of Solos. Also at the Skybase are two Solonians; Ky, who is a revolutionary, and Varan, a supporter of the Marshal's regime. They have been summoned for a conference with the Administrator, an official form from earth who has been sent to negotiate the terms of independence. But the Marshal does not want the Solonian independence which will mean the end of his rule and his return to an insignificant position on earth. So he engineers the murder of the Administrator by a Solonian native. He then imposes martial law and continues with his own plans. With the cooperation of a scientist, Jaeger, the Marshal plans to "oxygenize" the Solonians, thus making its high nitrogen content atmosphere suitable for earthmen, but unfit for native Solonians. He will then have command of an earth-type planet which he will be able to colonize and rule. The mysterious plague of mutations which is turning the Solonians into strange monsters is used by the Marshal as justification for his actions. Ky claims that the plague is being caused by pollution brought from earth. Ky is accused of the murder. In the confusion following the Administrator's death, he escapes back to Solos taking Jo with him as his hostage. The Doctor follows, and finds them in the unused Thaesian mines. The Time Lords' box clearly intended for Ky, opens revealing ancient tablets. The Doctor also finds Professor Sondergaard, an earth scientist driven into exile by the Marshal, and now living among the Mutants and trying to find a cure for their disease. The Marshal and his guards come in pursuit, blow up the mine entrance and flood the caves with gas. Stubbs and Cotton, two of the Marshal's guards, have realized what their master is trying to do, and they have become friendly with Jo and Ky. Together, the four escape to the surface. The Doctor insists on staying with Sondergaard in his underground laboratory, and with the help of the tablets, the two men try to find a solution to the problems of the Mutants. Jo and the others are captured by Varan, who turned against the Marshal when he discovered that the ruler had killed his son. He is now going to launch an attack on the Skybase, and insists that they accompany him. In the meantime, down below, the Doctor and Sondergaard come close to discovering the secret of the mutation when they find a mysterious cavern filled with glowing radio-active rock. Varan's attack on the base fails and he is killed. Jo, Ky, Stubbs, and Cotton are made prisoners. The Doctor and Sondergaard, on their way there, are hunted by the guards and are forced to split up. The Doctor reaches the Skybase, but he too, is taken prisoner. Using Jo has a hostage, the Marshal forces the Doctor to work with Jaeger in speeding up the oxygenization of Solos. Early experiments have gone very wrong, and the whole planet is in danger of contamination. By the same threat, the Marshal forces the Doctor to defend him before a tribunal headed by and Investigator from Earth. Proceedings are disrupted by Sondergaard who leads the surviving mutants in an attack. These, too, are defeated and the Marshal uses the opportunity to regain command. While the Doctor works with Jaeger on the oxygenization of Solos, the Marshal holds his friends prisoner in the Skybase radiation room. To the horror of the others, the radiation effects Ky, who begins to mutate before their eyes. Sondergaard injects the Solonian with a serum he and the Doctor prepared from a crystal found in the mysterious cavern. The Doctor deliberately sabotages the experiments, causing the Marshal to attempt to kill him, but Ky arrives. He has now mutated into a kind of super being, with amazing powers. Mutations are a natural part of the Solonian's life cycle, but they were triggered off too early by the Marshal's experiments with the atmosphere. Now that Ky has achieved the right mutation, he and Sondergaard can help the other Solonians to achieve their destiny.

(3o) THE TIME MONSTER - In a government research institute, Professor Thascalos is working on a matter transmission machine known as TOMTIT (Transmission of Matter Through Interstitial Time). In the meantime, at the Unit Laboratories, Doctor Who works on a Time Sensor, a device which detects disturbances in the time field - in particular those caused by the operation of the Master's TARDIS. The test run of TOMTIT produces a reading on the time sensor, and sends the Doctor and Jo down to the research center where a series of mysterious and terrifying events is taking place. And of course Professor Thascalos is the Doctor's old enemy, the Master. The Master's plan involves the Crystal of Kronos which long ago helped the rulers of Atlantis to control Kronos. This creature from outside time had tremendous powers which first brought prosperity and then destruction to the country. The Master sets off - back through time - to Atlantis, determined to seize the Crystal. With this he will have control of Kronos and thus power over time itself; a situation that could bring disaster to the entire universe. The Doctor and Jo pursue the Master through space and time to Atlantis where they try to stop him from taking the crystal. They are helped by Dalios, the wise old King of Atlantis, and hindered by his young and beautiful Queen Galleia, who side with the Master. In final struggle the full fury of Kronos is released, Atlantis is destroyed, the Doctor comes to a confrontation with the Master outside space and time. The Master is defeated, but once again escapes to work more mischief. DOCTOR WHO

(3p) CARNIVAL OF MONSTERS - Two visitors arrive on an alien planet, a far distance in time and space. They are Vorg, a wandering showman, and his girl assistant, Shirna. They bring with them the Scope, a kind of super-technological peepshow which maintains miniaturized, different life forms from all over the galaxy, kept in a simulation of their natural environments. The entertainers are met by a tribunal consisting of Kalik, Orum, and Pletrac, members of the planet's ruling class of Officials. In the meantime the Doctor and Jo come out of the TARDIS to find themselves apparently on board a cargo steamer chugging through the Indian Ocean in the year 1926.

Jo and the Doctor are separated and the Doctor escapes from the scope on his own, materializing to full size before the astonished Vorg and Shirna. The Doctor begins a struggle against Time to free Jo from the Scope, and return the other specimens to their rightful places. He also becomes involved in the revolutionary intrigues of Kalik and Orum, who are plotting to overthrow their superiors. By linking the TARDIS to the Scope, the Doctor manages to release Jo and return the other captive life forms to their own worlds and times. Vorg deals with the Drashigs who, thanks to the interference of Kalik and Orum, escape and materialize to their full size to rampage through the alien city.

In a confrontation in the Orgron's desolate land, the Doctor defeats the Master's plans and so prevents a space war. But as usual, the Master makes his escape, and so do the Daleks. Somewhere a mighty army is still waiting, determined to invade our galaxy. The Doctor and Jo set off in pursuit.

(3r) THE THREE DOCTORS - The Time Lords of Doctor Who's own planet are usually omnipotent, but now they find themselves faced by a problem which even they cannot solve. they are under attack from a mysterious "black hole" in space which is draining away their energies. They learn that a streak of "space lightning" emanating from the black hole is headed directly for Earth. Doctor Who, in the meantime, has been approached by Doctor Tyler, whose cosmic ray research balloon has picked up the track of a space lightning. Another of Tyler's research balloons comes back from space bringing a blob of mysterious animated gel. this promptly devours Ollis, a countryman who discovers the landed balloon.. the box containing the gel is taken to UNIT headquarters where it devours Tyler himself, rampages through the building, and eventually besieges the Doctor and Jo Grant inside the TARDIS. The Doctor sends and S.O.S. to the Time Lords. The Time Lords cannot help directly; all their powers are taken up in countering the drain on their energies. So as an emergency measure, they transfer the Doctor's previous selves from his earlier time streams. To his astonishment, Doctor Who is confronted by himself in his previous incarnation (played by Patrick Troughton) and finally by his third self in his first incarnation (played by William Hartnall). The three Doctors discover the incidents are caused by Omega, a bitter Time Lord who has been trapped behind the black hole in a universe of anti-matter for thousands of years. Omega wants the Doctor to take his place in his universe so Omego can return to the Doctor's. But it is too late - anti-matter radiation has already destroyed Omega's body, only his will remains and controls his world. Omega wants to destroy the Universe, but the Doctors offer him a positive-matter artefact, thus turning him into a supernova, whose energy will replenish the Time Lords' reserves. All three Doctors combine their forces, and more in sorrow than in anger bring about the destruction of Omega, so releasing him from the existence that has become a torment. Together, with his other victims, The Doctors return to the normal world. Here, the Doctor's earlier incarnations disappear, leaving Jon Pertwee with an irate Brigadier Lethbridge-Stewart, who is demanding a full explanation for the benefit of the United Nations Security Council.

Jo leaves the ship t get help, and at once is surrounded by the dangers of the weird jungle. Then she meets a party of Thals, the other inhabitants of Skaro, who were the Doctor's allies in his first encounter with the Daleks. They are on a suicide mission in an attempt to stop the monsters' latest attempt at world domination. The Doctor, now recovered, is rescued from the sponge-like growth which was choking the TARDIS, and the two parties join forces. They are hunted by Dalek patrols and they meet the Spiridon who have been enslaved and forced to yield their secret of invisibility. They discover geyser-like pools of molten ice. After many narrow escapes, they are at last able to use the power of the ice volcano to destroy their enemy. Jo develops a fondness for one of the Thals, but decides to return to her own planet.
