Chellak and his men attack Jek's base. The Dr crash lands the ship, and must escape from his captors, find the antidote to Spectrox poisoning and save Peri. He does so, but at the cost of his own life.

This story is notably one of few where the eventual outcome negates the importance of the plot. The Doctor's role provided no historical accomplishments, and instead caused an inadvertent massacre, a gigantic power collapse, and even his own "death", all of which could've been prevented had the Doctor never gotten involved (or even went to Androzani Minor, for that matter).
