The Doctor’s been everywhere and everywhen in the whole of the universe and seems to know all the answers. But ask him what happened to the Starship Brilliant and he hasn’t the first idea. Did it fall into a sun or black hole? Was it shot down in the first moments of the galactic war? And what’s this about a secret experimental drive? The Doctor is skittish, but if Martha is so keen to find out he’ll land the TARDIS on the Brilliant, a few days before it vanishes. Then they can see for themselves. . .

The old village well is just a curiosity – something to attract tourists intrigued by stories of lost treasure, or visitors just making a wish.

Who wishes to unleash the hideous force it contains? What terrible consequences will follow the search for a legendary treasure hidden at the bottom?

When the TARDIS makes a disastrous landing in the swamps of the planet Sunday, the Doctor has no choice but to abandon Martha and try to find help.

The human pioneers of Sunday have their own dangers to face: homeless and alone, they’re starting to see that Sunday’s wildlife isn’t as harmless as it appears. Why are the otters behaving so strangely, and what is the creature in the swamps that is so interested in the humans, and the new arrivals?

A huge and hungry alien creature is heading remorselessly towards their home. When it arrives everything will be devoured.

It is almost Halloween in the sleepy New England town of Blackwood Falls. Leaves litter lawns and sidewalks, paper skeletons hang in the windows, and carved pumpkins leer from front porches. The Doctor and Martha soon discover that something long-dormant has awoken, and this will be no ordinary Halloween. What is the secret of the ancient tree and the book discovered tangled in its roots? What rises from the churchyard at night, sealing the lips of the only witness? Why are the harmless trappings of Halloween suddenly taking on a creepy new life of their own?

A vast starship, seemingly deserted, is spinning slowly in the void of deep space. Martha and the Doctor explore this drifting tomb and discover that they may not be alone after all.
