Blake's 7Avon calls a summit meeting of the most powerful non-Federation-aligned worlds’ leaders to devise a plan to combat the Pylene-50 pacification drug, but his most powerful ally, Zukan, turns out to be an underground informant for Servalan and plants explosives in Xenon Base. The base explodes while Avon and Soolin are en route to rendezvous with a source of vital raw material. Zukan later discovers that his own daughter has stayed behind on Xenon to remain with Tarrant, and Avon manages to save his crew just in time, but Zukan’s daughter dies while reactivating the Xenon Base life support systems.
