The legendary Paradise Towers is supposed to be the height of luxury but when the Doctor and Mel arrive, they find it is as far from paradise as possible...

With the Doctor condemned to death by the caretakers and their bizarre rulebook, Mel faces cannibalistic OAPS. Is Pex going to be the true hero of Paradise Towers ?

Mel and Pex play cat and mouse with the lethal cleaner robots while the Doctor and the surviving Kangs learn all about Kroagnon the Great Architect.

Meeting up at the pool, the Doctor leads the surviving Rezzies, Kangs and Caretakers as they draw the line together on the 245th floor against the systematic cleansing of all life by Kroagnon and his robotic Cleaners.

The Doctor and Ace visit the Psychic Circus on the planet Segonax, where they find the standard of judging at the talent contest distressingly astringent.

The Doctor and Ace reach the Psychic Circus, where the Doctor is imprisoned with the other contestants while Ace draws the attention of the Chief Clown.

Mags helps the Doctor escape and Deadbeat leads him to Ace, where Bellboy tells them what happened to the Psychic Circus.
