S4 E1 • The Smugglers (1)

Ben and Polly's first trip by TARDIS takes them to the 17th-century Cornish coast, in the era of smugglers and pirates. There, the Doctor receives a clue to the location of hidden pirate treasure – making him a target for the vicious captain Pike. His interrogation is delayed when a smuggler named Jacob Kewper contacts Pike, erroneously believing him to be a fellow smuggler; when Pike learns that the local Squire is the head of a smuggling ring, he decides to impersonate a smuggler, learn the location of the smugglers' hoard, and then kill them all and acquire the goods for himself. The Doctor and Kewper manage to escape, but Kewper goes straight to the Squire with news of the hidden treasure. The Doctor and his friends have only one ally – Revenue man Josiah Blake, who has been investigating smuggling in the area but now finds that all hell is about to break loose. While Blake rides for the militia, the Doctor struggles to decipher the clue he's been given, knowing that only by locating the treasure himself can he bargain with the pirates and smugglers and prevent a battle which will inevitably result in the deaths of innocent townsfolk.

S4 E5 • The Tenth Planet (1)

The TARDIS materialises decades in the future, in the year 1986, at Snowcap Tracking Station at the South Pole. There, an international team is struggling to bring down a shuttle which has inexplicably been drawn out of orbit – by the gravity of a tenth planet, Earth's exact mirror twin. The Doctor realises what's about to happen, but before he can deliver his warning, Snowcap is invaded by the Cybermen – natives of the planet Mondas who have slowly replaced most of their body parts with cybernetic prostheses, and who have now returned to their twin to drain the energy away from Earth. However, the Doctor and his friends soon find themselves fighting a threat closer to home – in order to save his astronaut son, the American General Cutler intends to attack Mondas with a Z-Bomb despite the danger that the radiation from the explosion will render half of Earth uninhabitable. The Doctor realises that the Cybermen have invaded Earth because Mondas is drawing away too much energy, and that their best hope is simply to stall the Cybermen until Mondas explodes of its own accord. But the energy drain is affecting the elderly Doctor's health, and when he finally returns to his TARDIS he collapses – and before Ben's and Polly's eyes, he seems to change into an entirely different person...

S4 E9 • The Power of the Daleks (1)

The Doctor appears to have transformed into an entirely different person, but Ben and Polly are unsure whether this strange man really is the Doctor or not. They soon have other matters to worry about, as the TARDIS takes them to a human colony on the planet Vulcan. Rebel activity is causing trouble for the colony governor, an Earth Examiner has recently been murdered, and the colony scientist Lesterson is obsessed with his experiments on an alien capsule unearthed from the mercury swamps. The Doctor takes the Examiner's place in order to investigate his murder, but soon discovers that the alien capsule is far more significant – for it contains dormant Daleks which Lesterson has woken. Lesterson believes that the Daleks are harmless robots which can be used to serve the colony, while the rebels are far more interested in the uses of the Daleks' in-built weaponry. Nobody will listen to the Doctor when he warns them that the Daleks have their own agenda – one which could result in the extermination of all human beings in the colony.

S4 E15 • The Highlanders (1)

The TARDIS materialises on Culloden Moor just after the rout of the Jacobite rebels in 1745. The British army is mopping up survivors, and when they find the Doctor and Ben in the company of rebels they are accused of desertion and arrested. They are saved from execution by Solicitor Grey, the Commissioner of Prisons – but he has his own agenda for the prisoners. Imprisoned in Inverness, the Doctor realises that Grey is running a scam of his own, removing rebels from the prisons with the promise that they will be saved from execution if they sign contracts binding them to service in the Jamaican plantations. In short, he's a slave trader. While the Doctor and Ben try to find a way to escape and help their new friends, Polly and Kirsty MacLaren, whose father has been kidnapped by Grey, blackmail an English officer into helping them locate their kidnapped friends and family. The Doctor and his companions must then find their way back to the TARDIS through a battlefield, and the young Highland piper who helps them, Jamie McCrimmon, accompanies them on their travels.

Trying to take his companions to Mars, the Doctor instead ends up on the Moon in the year 2070. Earth's weather is controlled by means of gravity waves directed from an internationally-run Moonbase, but the staff of the Moonbase are suffering from a mysterious outbreak of plague, and moments after the Doctor and his friends enter the entire Moonbase is placed under quarantine. The Doctor offers to help find a cure for the plague, which he suspects is no plague at all – and he's right. The base's food supplies have in fact been poisoned by Cybermen from the colony world Telos, who intend to seize control of the Graviton and use it to destroy the Earth – not as revenge for the destruction of Mondas, but simply and logically to eliminate a potential threat.

But a madman named Medok claims that the camp is stalked at night by hideous monsters, and as the Doctor learns more about the camp he realises that the people here risk their lives daily to mine a dangerously toxic natural gas – and yet nobody knows what it's for. His investigation attempt hits a snag when Ben is brainwashed by the colony's subliminal conditioning, and turns in his friends for acting against colony interests. In fact, the colony is under the control of the Macra, giant crab-like insects who are using the brainwashed humans to mine the gas they need to survive. It's up to the Doctor and his friends to prove the truth and free the colonists from a slavery they don't even know they're suffering.

She tells the Doctor, but is then kidnapped – and reappears shortly afterwards, bearing a passport from Zurich and claiming to have no idea who the Doctor is. Jamie meets a young woman named Samantha who's looking for her missing brother, and when a detective from Scotland Yard shows up looking for his missing colleague, the airport Commandant is forced to concede that something very odd is going on. The Doctor soon discovers that "Chameleon Tours", ostensibly offering cheap package tours for students and hitch-hiking youths, is in fact a front for a massive kidnapping operation. The alien Chameleons, who lost their personal identities in a cosmic accident, intend to steal the identities of the thousands of kidnapped youths, and the Doctor and his friends must stop them. When the situation is resolved, Ben and Polly discover that this is the very day on which they began travelling with the First Doctor, and choose to remain in London.

Jamie meets a young woman named Samantha who's looking for her missing brother, and when a detective from Scotland Yard shows up looking for his missing colleague, the airport Commandant is forced to concede that something very odd is going on. The Doctor soon discovers that "Chameleon Tours", ostensibly offering cheap package tours for students and hitch-hiking youths, is in fact a front for a massive kidnapping operation. The alien Chameleons, who lost their personal identities in a cosmic accident, intend to steal the identities of the thousands of kidnapped youths, and the Doctor and his friends must stop them. When the situation is resolved, Ben and Polly discover that this is the very day on which they began travelling with the First Doctor, and choose to remain in London.

S4 E37 • The Evil of the Daleks (1)

The TARDIS is stolen from Gatwick Airport, and when the Doctor and Jamie investigate they stumble into a trap set by Edward Waterfield, a time-traveller from the year 1866. His daughter Victoria has been kidnapped by the Daleks, in order to force him to lure the Doctor into their clutches. The Daleks have realised that human beings possess unique qualities which have enabled them to defeat the Daleks on every occasion the two races have fought; thus, the Daleks order the Doctor to monitor Jamie while he attempts to rescue Victoria, and synthesise the elusive Human Factor, which they intend to add to their own genetic makeup. The Doctor does so, and as he'd hoped, the test Daleks imbued with the Human Factor become playful and friendly. However, the Dalek Emperor then reveals that his real intention was to isolate the Dalek Factor and force the Doctor to spread it to the rest of humanity. The Emperor's plan fails, however, as the Doctor is not human and the Dalek Factor has no effect on him. The Doctor therefore tricks the Emperor into administring the Human Factor to several more Daleks, who begin to question authority and rebel against the Emperor. Waterfield dies saving the Doctor's life, and the Doctor and Jamie take Victoria with them as they depart, leaving the Dalek factions to fight each other to the death.
