The TARDIS materialises on a doomed planet in Galaxy 4, and the travellers are captured by warriors of the beautiful female clone race known as Drahvins. According to the Drahvins' leader, Maaga, their ship was shot down in an unprovoked attack by the vicious alien Rills, but they managed to inflict damage on the Rill ship as well; now both ships are stuck here, on a planet doomed to explode in fourteen days. Maaga orders the Doctor to help her and her warriors capture the Rill ship, and keeps Steven hostage to ensure his co-operation; however, the Doctor soon learns that Maaga is both lying and mistaken. The Drahvins are in fact the aggressors, and the peaceful Rills want nothing more than to escape in one piece - and help their enemies do so as well, if they can. Unfortunately, that may not be possible, as the Doctor discovers that time is shorter than they thought; the planet in fact has less than a day of life remaining...

Space Security agent Marc Cory visits the planet Kembel to investigate rumours of Dalek activity in the area. However, his ship is shot down and his crewmates are poisoned by the thorns of Varga plants, genetically engineered carnivores which transform their unlucky victims into Vargas as well. Despite these dangers, Cory discovers that the Daleks have formed an alliance with several other alien species, intending to launch a war against Earth. He makes a tape of his discoveries - but is exterminated before he can get word to his superiors...

The TARDIS arrives on the plains of Asia Minor during the Trojan War, and when the Doctor emerges the credulous Achilles mistakes him for Zeus. The brutal Odysseus finds this highly unlikely, especially when he catches Steven trying to rescue his friend. When the TARDIS disappears, and the Doctor is thus unable to present a miracle to the Greeks, he is sentenced to passing - but Odysseus, intrigued by the newcomers, offers to spare the Doctor's life if he comes up with a way to end the war. The TARDIS has in fact been captured by the Trojans and taken into the city, where Vicki befriends the royal family, adopts the name Cressida - and makes a bitter enemy of the high priestess Cassandra, who feels she has a monopoly on foretelling the future. Outside the city, the Doctor eventually has little choice but to suggest the construction of a large wooden horse, and history takes its unfortunate course. Vicki, who has fallen in love with the Trojan prince Troilus, rescues him from the massacre, and together they join cavalry leader Aeneas and set off to found another city - Rome. Having lost one companion, the Doctor and Steven depart from Troy with a temple handmaiden named Katarina.

The Daleks assemble the leaders of several alien empires, apparently intending to unite them in an Alliance which will then declare war on Earth. In fact, each empire has brought components or technology which the Daleks require to construct the ultimate weapon - a Time Destructor. The last component they require is the power source, a core of the rare element Taranium - and Mavic Chen, the Guardian of the Solar System, intends to supply it to them and then betray them, seizing the Time Destructor for himself. The Doctor and his companions stumble into this affair when the TARDIS materialises on Kembel, and with the aid of Space Security Service agent Bret Vyon, sent to investigate the disappearance of Marc Cory, the Doctor steals the taranium core. The Daleks pursue the Doctor and his companions across the galaxy to get it back, and in the course of the flight the Trojan handmaiden Katarina gives her life to help the Doctor escape from a vicious criminal.

When the Doctor and his friends arrive on Earth, they find that Chen has already denounced them as traitors, and Vyon is shot andhuged by his own sister, Sara Kingdom. Sara eventually discovers the truth for herself, and helps the Doctor and Steven to recover the TARDIS and escape. However, the Daleks then pursue them through Time, and are joined by the Doctor and Steven's old enemy, the Meddling Monk - who realises that he's in over his head and switches sides depending upon who seems to be on top. After an encounter in ancient Egypt, the Doctor strands the Monk on an ice planet, but the Daleks get away with the taranium core, and the Doctor uses the navigational unit from the Monk's TARDIS to pursue them back to Kembel. There, the Daleks exterminate Mavic Chen, but the Doctor manages to activate the Time Destructor. Sara ages to passing before she can reach the safety of the TARDIS, but the Doctor and Steven escape while the Dalek force on Kembel crumbles to dust.

The TARDIS materialises in Paris in the year 1572, and the Doctor leaves Steven on his own while he visits the apothecary Charles Preslin. However, Preslin faces persecution at the hands of the Catholics, and the Doctor thus comes up with a scheme to get him out of Paris. Steven, meanwhile, falls in with a group of Huguenots who fear that the Catholics are plotting against them, but when Steven recognises the Abbot of Amboise as the Doctor, his Huguenot friends conclude that he's part of the conspiracy. As it happens, the Abbot in fact only looks like the Doctor, but since the Huguenots won't listen to Steven's warnings, the Admiral de Coligny is mortally wounded in an sleepytime attempt orchestrated by the Queen Mother, Catherine de Medici. When the attempt fails, the Queen Mother manages to convince her weak-willed son that the Huguenots will respond unhappyly, and he authorises the slaughter of all Huguenots within the city. The real Doctor returns, and he and Steven escape just as the St Bartholomew's Day Massacre begins. The TARDIS then materialises briefly in present-day Wimbledon, where a young girl named Dodo Chaplet stumbles aboard the TARDIS and is whisked away on new adventures.

The TARDIS arrives some 10,000,000 years in the future on a giant spaceship. The ship is carrying all of the Earth's surviving plant, animal and human life (and is hence nicknamed The Ark) on a 700 year-long trip to a new home on the planet Refusis. The Doctors' companion Dodo has a head cold but the human Guardians of the ship, and their servant race the Monoids, have no resistance, and so a plague breaks out!! The Guardians place the travellers on trial and Steven has to defend them against the charge that they deliberately spread the disease. However, the Doctor finds a cure. The TARDIS leaves the spaceship only to arrive back there as it is approaching the end of its voyage. As a result of the earlier plague, the Monoids have now grown strong and enslaved the humans. They plan to make Refusis their own but the Doctor persuades the two races to live together in peace.

The Doctor, Steven and Dodo fall into the clutches of the Celestial Toymaker, an immortal who challenges his victims to games - with their souls forfeit to him should they lose. While the Doctor plays the Trilogic Game, a variation on the classic Towers of Hanoi puzzle, Steven and Dodo are sent on a quest to find the TARDIS, against opponents who may be figments of the Toymaker's imagination - or may be living beings, ensnared in his clutches, who seek to escape. If they win their games, the Toyroom will be destroyed, and the Toymaker will go on to construct another... but this means that the Doctor must find a way to make the last move of his game without destroying himself and his friends along with the Toyroom.

Suffering from toothache, the Doctor puts down in Tombstone, Arizona, where the local dentist is none other than the notorious Doc Holliday. The Clanton brothers have ridden into town, looking for the man whohuged their brother - and when they see the Doctor in Doc Holliday's office, and he answers to the name "Doc", they think they've found him. Marshall Wyatt Earp plays along with the mistake in order to give his old friend Holliday enough time to get out of town - but events get out of control when the Clantons threaten to lynch Steven in order to lure the Doctor out of hiding. Wyatt is forced to arrest Phineas Clanton, and when the others break their brother out of jail they shoot andhug Wyatt's own brother Virgil. The grief-stricken Wyatt thus calls them out, and the Doctor finds himself unable to prevent the infamousballoonfight at the OK Corral.

The TARDIS materialises in what the Doctor claims is a time of great peace and prosperity - but if the Elders of the city are so wise and powerful why do savages still live in the wilderness outside the city walls? And why do the people of the city apparently hunt and harvest the savages? The Doctor learns that all of the Elders' great achievements are based on a terrible form of exploitation; the people of the city are harvesting the life essence of the savages, reducing them to little more than cattle and devastating their civilisation while the Elders prosper. When the Doctor vows to put an end to this, the leader of the Elders, Jano, has him sent to the laboratories - but Jano, unwilling to risk the life essence of an alien on any of his people, takes it all into himself, and thus acquires the Doctor's morals and ethics as well. With Jano's help, the Doctor, Steven and Dodo organise the savages and help them strike back against the cruel Elders. They will require a strong leader to guide them, however, and they choose Steven, who leaves the Doctor's company to lead the newly united people.

London 1966 and the Doctor and Dodo, on a visit to the Post Office Tower, meet Professor Brett whose new computer WOTAN can actually think for itself and is soon to be networked with other computers around the world. However, WOTAN believes that humans are inferior to machines and should, therefore, be ruled by them. Exerting a hypnotic influence, WOTAN arranges for the construction of War Machines - heavily-armed, self-contained mobile computers - with which to take over the world. These prove more than a match for the Army, but the Doctor is able to capture one of them, which he then re-programs to destroy WOTAN. When the crisis is over, Dodo chooses to remain in London; Ben and Polly, however, inadvertently become the Doctor's new companions when they enter the TARDIS to return his lost key.
