The TARDIS arrives on the planet Terra Alpha, where the Seventh Doctor and Ace discover a society in which sadness is against the law - a law enforced zealously by the brightly uniformed Happiness Patrol. The planet is ruled by Helen A with the aid of her companion, Joseph C, and her carnivorous pet Stigorax, Fifi.

The arrival of a mysterious comet heralds impending danger from enemies both old and new. As Ace helps the Doctor defend Earth, she is confronted with a dangerous question..."Doctor Who?"

As trouble brews on the space trading colony of Iceworld, the Doctor and Mel encounter their sometimes-ally Sabalom Glitz and a new friend who goes by the name "Ace".

The Doctor and Mel go for a holiday trip to Shangri-La aboard a Nostalgia Tours bus, only to get dragged into the battle against genocide of their fellow passenger Delta, a Chimeron Queen fleeing from the Bannermen who wish to make her species extinct.

As evidence for the defense at his ongoing trial, the Doctor presents an adventure from his future when he is travelling with a computer programmer named Mel. Answering a mysterious distress call from the space liner Hyperion III, they find that the passengers aboard include unscrupulous scientists, secret agents, saboteurs, thieves and a murderer. And lurking in the shadows are the Vervoids, the product of sinister botanical experiments, who will stop at nothing to destroy all non-plant life.

Charged with genocide by the treacherous Valeyard at his trial, the Doctor receives help from an unlikely source to turn the tide of the High Council's rulings in his favour and reveal the Valeyard as a wrongdoer: the Master. For the Valeyard's own crimes are so atrocious, even the Doctor's archenemy will help him to ensure that the villain won't see the light of day again. Cornered, the Valeyard flees to the Matrix, where he can be the Doctor's judge, jury and executioner...
