There the Doctor is taken prisoner after he discovers a strange object in a Death Zone and brought to the ruthless Lady Adastra. Meanwhile, Romana is taken prisoner by a tribe of savage men.

The Doctor escapes Lady Adastra by jumping down the pit into the only metal mine on Chloris, there he encounters a astrologer that was thrown into the mine by Adastra and is still alive. Meanwhile Romana is coerced by Lady Adastra to reveal the secret of the giant egg like object.

While in the pit. the Doctor with the help of the old astrologer, seeks to establish what the creature is. While attempting to make contact with the strange creature Lady Adastra and her entourage arrive in the mine in search of the Doctor who they now believe might possibly still be alive. Meanwhile, the tribe of savage men raids the home of Lady Adastra of her metals.

Two spaceships have a hyperspace collision and become locked together causing the area where they are connected to become unstable due to the intersection of the hyperspace fields. The Doctor and Romana arrive and become involved. The Doctor discovers a crewman using the dangerous drug Vraxoin.

The Doctor and Romana are horrified when they discover that Tryst has live lifeforms stored in his CET machine. The Doctor and Romana continue their search for the narcotic smuggler. When law enforcement officers show up on the ship, the Doctor and Romana immediately become suspects due to their lack of any identity documentation and flee.

While being chased by the customs officials as smugglers, the  Doctor and Romana work to both track down the smuggler and to separate the two ships. During all this excitement, multiple Mandrels have escaped from the CET machine and the Doctor discovers their secret.

The Doctor solves the problem of who the smugglers are and how they are transferring the drugs. With the help of the Doctor and Romana, Stott and Fisk make plans to capture the culprits before they can escape.

The Doctor decides to modify some of the TARDIS's systems, so disables most of the major ships systems. During this process, they encounter a stranded ship from Skonnos. They the assist the remaining crew member who then kidnaps Romana and leaves the Doctor stranded in the TARDIS.

Upon arriving on Skonnos, Romana and the Athenian sacrifices are forced into the power complex of the Nimon. The Doctor then arrives on Skonnos searching for the missing Romana.

As they travel deeper into the Nimon power complex, the Doctor and Romana start to suspect that there is a lot more to the Nimon than meets the eye and that they may be seeing the start of a invasion of the planet Skonnos.

Arriving on the dying world of Crinoth at the other end of the black hole transmat system the Nimon has built, Romana discovers the truth behind the motives of the Nimon and their promises to the people of Skonnos. The Doctor then attempts to foil the invasion plans before the Nimon horde can arrive.

The Doctor and Romana visit Chronotis, a retired Time Lord living in Cambridge, who admits that he's lost a book dating back to the time of Rassilon and needs their help to find it. In fact, he's accidentally lent it out to graduate student Chris Parsons, who soon realizes that this is an extraordinary text indeed. The book is also sought by the evil scientist Skagra, who has developed a sphere capable of drawing its victims' minds out of their bodies. Skagra needs the book to reach the Time Lord prison Shada, which even the Time Lords have forgotten. Long ago they imprisoned the criminal Salyavin there, as punishment for using his powers to transfer his mind into other people's bodies. Chronotis is eventually forced to admit that he himself is Salyavin; he escaped long ago and used his powers to cause the Time Lords to forget about his prison. However, he's now repented of his crimes and wishes to live a quiet, peaceful life. Skagra drains Chronotis's mind and thus acquires the ability to transfer his own mind into other bodies; with the aid of the sphere and his crystalline servants, the Krargs, he will spread his own mind throughout the Universe and become immortal. However, when the Doctor pretends to be stupid, the sphere fails to drain his mind completely. He thus survives, and since there's a copy of his mind inside the sphere, he is able to use the resonance to turn Skagra's possessed slaves against him. Skagra is imprisoned by his own Ship, and Chronotis returns to Earth to resume his peaceful retirement.
