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.

The Rani has returned with another malicious scientific scheme. Taking advantage of the post-regenerative trauma the recently regenerated and unstable Doctor is going through, she hopes to achieve control of an approaching asteroid composed entirely of strange matter. Can the Doctor figure out he is being used for the Rani's evil experiment, and what is behind the door the Rani won't allow him past?

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...

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.

As the Doctor's trial continues, evidence is presented showing his most recent adventure, one where he faces an old adversary, Sil. As a scientist conducts his unethical experiments to prolong the life of Sil's boss Kiv, the Doctor's memories of the events begins to return and an unpleasant surprise awaits him.

The Doctor is summoned before the High Council of Time Lords to stand trial for the charges of harmful interference to the course of events during his travels which have threatened the sanctity of the universe. Indignant at these accusations, the Doctor pleads his case to the Inquisitor with the hope that she will see him as a source of hope and goodwill for existence. However, his prosecuting attorney, a sinister Time Lord known simply as the Valeyard, begins a crusade against the Doctor with the motive of framing him as a villainous renegade.
