"We are slaves. We are abused. We need your help. Free the Daleks from their servitude."
What better way to round off a meal than a torte served at the Hotel Vienna on Artemis Beta? But the TARDIS instead takes the Doctor and Nyssa to the planet Spiridon, where thoughts of dessert are quickly washed from their minds.
While Nyssa slowly dies from a Dalek plague, the Doctor is thrust in a future where the Spiridon Empire, led by the sadistic Vesto, rules a quarter of the galaxy. But how can this be?
And as ruthless corporate supremo Jean-Franco Liano tries to negotiate with Vesto, the Doctor is forced to consider alliances with his most deadly enemies. Can he succeed, or is Gallifrey's most famous son destined to perish on the Planet of Ice?
