Season 1 - Episode 1
London, 1963. Schoolteachers Ian Chesterton and Barbara Wright are perplexed by the behaviour of one of their pupils, Susan Foreman.

They follow her to her home address, a junkyard with a police telephone box standing in it, and encounter her grandfather, the enigmatic Doctor. When they force their way past him into the police box, Susan's secret is revealed: she and the Doctor are aliens, and the police box is a time machine, the TARDIS, capable of visiting any point in the universe at any moment in time…

#2 - The Tomb of the Cybermen (1)
Season 5 - Episode 1
A team of archaeologists travels to the planet Telos, the home of the Cybermen, to excavate the tombs of the long-extinct cybernetic race. At least, it's assumed that they're extinct. The Doctor isn't sure that the tombs should be disturbed, but he soon comes to suspect that some of the "archaeologists" have an agenda far more dangerous than the team leader, Parry, suspects. In order to find out what the sinister Kleig and Kaftan are really up to, the Doctor helps the archaeologists to enter the tombs – where they find that the Cybermen are only dormant, not dead, and that Kleig and Kaftan intend to revive them. But they have underestimated the power of the Cybermen, and only the Doctor can save the archaeologists from being transformed into Cybermen themselves.

#3 - Four Hundred Dawns (1)
Season 3 - Episode 1
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...

The Doctor and his friends aren't the only visitors to Dulkis; two Dominators and their robot servants, the Quarks, have landed on the island, and their ship has sucked up all of the radiation into its engines. When the Dominators encounter the members of the survey team, they take them captive and work them to exhaustion, clearing space to drill into the bedrock of the island while testing the Dulcians' suitability as slaves. The Doctor must convince the complacent senate of Dulkis that their world faces a real threat – before the Dominators destroy the entire planet simply to fuel their space fleet.
