Publisher's summary
In the Vortex, the TARDIS comes under a form of psychic attack — resulting in the abductions of first Adric, then Tegan. Following their trail, the Doctor and Nyssa arrive under the lurid skies of the planet Zaltys, whose entire population has vanished in strange circumstances. Soon, they discover that Zaltys is now the target of treasure seekers, come to scavenge this so-called Planet of the Dead...

Meanwhile, deep below the planet's surface, Adric learns the earth-shattering reason why the people of Zaltys disappeared... and why they were wise to do so. And Tegan is, quite literally, in the dark – enduring interrogation by the mysterious Clarimonde. Any friend of the Doctor's is Clarimonde's enemy... because theirs is a blood feud!

Part one
Tegan interrupts Adric whilst he is reading Dracula in his bedroom and, given the Doctor's lack of success, gets him to try flying the TARDIS to Heathrow. However, the Doctor and Nyssa have been doing repairs which involved disabling the chrono-compensator, causing Adric to disappear after hearing a voice mention Zaltys. The Doctor uses the telepathic circuits to track him down, with Tegan disappearing as well on the way.

When the Doctor and Nyssa arrive on Zaltys, they meet Sable, who accuses them of being after the planet's treasures and insists that they accompany her. She explains that Zaltys has been under quarantine since communication from the planet suddenly ceased seven months ago and points out a possible entrance to their underground city. Sable's partner, Siobhan, attempts to give her a warning and proceeds to abandon her, flying away in their spaceship and leaving Sable suspecting that there might be a plague.

Adric appears in a corridor whilst Tegan appears in a locked room. Using an ion bonder from the TARDIS, Tegan escapes the room and is watched by Clarimonde, who tells her that her people are enemies of the Doctor and encountered him when he was travelling with Jo Grant. Clarimonde gets her to open a hatch containing the body of a woman who attacks her. Tegan tells it to get back.

Part two
Tegan forces the woman back through the hatch from which she is ejected into space, revealing that Tegan is on the Exemplar spaceship. Clarimonde approaches Tegan and tells her that she has forty minutes to run, after which the crew will wake up and hunt her down to amuse themselves before they land. When she refuses to do so, Clarimonde demonstrates her super-strength and threatens her.

Adric accesses a computer, claiming to be Perrault, one of the most recent people to log into it, and learns of a meteor expected to hit Zaltys in two hours. He runs away when Gevaudan, a telepathic Vulpine, approaches, but Gevaudan hears that the computer has been being used and informs Perrault and Talia of possible intruders. After Gevaudan captures Adric, Perrault shows an interest in him and asks about his planet, but Talia is suspicious of him as she is all aliens.

The Doctor, Nyssa and Sable enter the city and find the inhabitants in cryo-sleep and split up to look for Adric and Tegan, with the Doctor soon discovering that Adric has accessed the computer system and locating the particular terminal. Finding no clue as to his whereabouts, he goes to the command centre and sees him being held at gunpoint by Talia on a monitor.

Part three
Tegan realises from the husk and the lack of windows that the crew of the Exemplar are vampires. As they advance upon her, the fish-person Lusca gets her to safety through the ducting system.

Sable shoots Talia with helicon energy before she can kill Adric. After she, Adric and Nyssa leave to look for Tegan, the Doctor gives Talia medical attention.
