Doctor Who - Season 15 (1977)

With little to fear, and its mother ship about to land and turn Earth into an alien attack base, the electrically charged Rutan scout drops its human guise and attacks openly.

In the year 5000 AD a three-man crew arrive on the planet Titan but unknowingly become hosts for an alien virus that turns them hostile. Picking up a distress signal in the Tardis, the Doctor and Leela head to the planet to investigate.

The Doctor draws into himself, fighting the voice in his own head that's trying to take over his intelligence.

The medical center mounts a defense against alien forces trying to take the comatose Doctor while clones of Leela and the Doctor go microscopic so they can hunt down the intelligent infection that's in his head.

In trying to retrieve the clones from inside the Doctor, the alien virus is brought from the microbial world into the macro-world, and it's ready to spawn.

Archeologists near a reputedly haunted woods use a time scanner to explore the history of a sinister 12 million year old skull, creating a hole in time that attracts the Doctor's attention.

Every time the archaeologists explore the ancient skull, something deadly hunts and haunts the wood while one of the researchers is particularly affected.

The Doctor endeavors to prevent the re-existence of a Fendahl, a group entity that feeds on life itself and thought only to exist in Time Lord mythology, but a witches' coven, seeking power, intervenes.

With one of the archaeologists transformed and a massive implosion threatening, the Fendahl and its Fendahleen components start coming into existence while the Doctor, Leela and the Tylers do what they can to stop it.

The Doctor and Leela land on Pluto in the far future and discover that it's inhabited by humans. Leaving K9 in the Tardis, the pair meet a man contemplating suicide after he's unable to pay his father's "death tax".

Captured by the authorities, the Doctor finds himself restrained in a Correction Centre where he's to be prepped for painful shock treatments, making him unable to return within a given time frame to the underground rebels holding Leela, who are prepared to kill her as promised.

The merciless Collector, who runs The Company, issues a bounty on the Doctor for his capture, while an already captured Leela is sentenced to public execution, via a steamer, for crimes against the company.

Attempting to start a successful revolution, the Doctor uses Pluto's Public Address System to announce successful revolution, all the while trying to determine the Collector's true species and why he, or it, seems set on taxing the life out of humans.

Materializing at the edge of the cosmos, the frontier of creation, The Doctor, Leela & K-9 encounter four ancient space travelers from Minyos, the first race ever contacted by the Time Lords. All but extinct due to their Time Lords encounter, the Minyans (rejuvenated 1000 times each) have been embarked on a long 100,000 year old quest, searching the universe for the lost race bank of their species to take to a new home world. But their equally old ship is finally failing, succumbing to the gravitational pull of a newly forming sun and taking the Doctor and his party ...

Crashing inside a newly formed planet, the Doctor and others find it inhabited by a slave labor mining society, where rocks are harvested for their radioactive energy and human life has little value. With a population controlled by deliberate cave-ins, poison gas, and periodic sacrifices to an Oracle, the miners, called Trogs, are also descendants from Minyos, and who desperately desire freedom.

Capturing the Doctor and Leela, the citadel guards are quite pleased to have more subjects for their public executions, but it only fires up a Trog revolt instead.

With the Trog revolt close to success, the Oracle grants the Minyos travelers what they seek (the long lost race bank) in hopes they'll depart peacefully and straight away, but the Doctor suspects it's not all going to be as amicable as that. And what to do about the Trogs?

After signing a contract in secret, the Doctor returns to Gallifrey with Leela and K9 in order to claim his title as the President of the High Council of the Time Lords.

The Doctor orders Leela exiled from the Capitol, then orders K9 to sabotage Gallifrey's defences.

The Doctor allows the Vardans to occupy Gallifrey while Leela and Rodan head out into the wasteland to search for help.

The Doctor convinces Andred to trust him as he works to expel the Vardans, while Leela gathers the Outsiders for an attack on the Capitol.

The Doctor and his friends flee from the Sontarans and the Doctor tries to convince Borusa to abandon his sacred office in order to help defeat them.

The Doctor and his friends take refuge in the TARDIS but find themselves pursued by Stor and Kelner.
