Publisher's summary
Shortly after surviving the perils of Logopolis, Castrovalva and the machinations of, the new Doctor and his new crew could be forgiven for wanting to take a breather from their tour of the galaxy. But when the TARDIS lands in a strange and unsettling environment, the urge to explore is irresistible... and trouble is only a few steps away.

The world they have found themselves in is populated by a wide variety of the strangest people imaginable - a crashed spacecraft here, a monastery there, even a regal court. And not everyone they meet has their best interests at heart.

With the TARDIS stolen and the very environment itself out to get them, the travellers face an extremely personal threat. They'll have to work as a team if they want to get out alive... but can you really trust someone you barely know?

Part one
Tegan is shown to her bedroom aboard the TARDIS by Adric, whom she does not like nor trust and who is disillusioned with life on the ship since losing his Doctor. Tegan and Nyssa discuss the death of Vanessa and the destruction of Traken before following the new Doctor and Adric outside, finding themselves on a world from which Nyssa gets a feeling of foreboding. The four of them head back to the TARDIS, but tribespeople are carrying the ship away and the Doctor and Adric follow, leaving Nyssa and Tegan behind.

Unhappy with this, Tegan removes her heels and she and Nyssa go after them, but soon get lost. Nyssa and Tegan meet adventurer Professor Rickett and his companions, Perditia and Magpie, who take them to their base camp. When the camp is attacked, Nyssa and Tegan run and head towards a citadel, but they are found by Erdos and brought before King Magus and his mother, Queen Antigone, who refuse to let them leave for their own safety.

The Doctor and Adric are noticed by the tribespeople and chased until they are saved by two scientists: Denyx and his daughter, Zaria. The scientists take them to their crashed colony ship, where the Doctor learns that Nyssa and Tegan have wandered off and that they will be in danger from savage creatures once night falls. Adric is given a tour of the ship and challenges Zaria to rebel against the strict lifestyle there by going with him outside of the ship without permission. The Doctor opens a sealed hatch to go after them, but Flight Coordinator Javon orders him at gunpoint to close it. In the caves, Adric and Zaria encounter giant spiders.

Part two
Professor Rickett, Perditia and Magpie board the colony ship and keep Javon from punishing the Doctor for opening the hatch through which they were able to escape the tribespeople. They join the Doctor in going after Adric and Zaria and are led to a monastery by Pyrrha, a sceptic whose associate, theoretical mathematician Calcula, saved the two of them from the spiders.
