Gan, Avon, Vila and Jenna have fallen ill with potentially lethal radiation sickness after spending too much time on the irradiated surface of Cephlon. Their only hope is that the mysterious Ensor that Blake plans to contact on Aristo has a supply of drugs to cure the illness. On the surface, however, Travis and Servalan have arrived early and make their way slowly and clumsily to Ensor’s underground installation. Blake and Cally teleport to the surface as well and are accosted by a flying object that gives them precise instructions to reach a hidden lift leading directly to Ensor’s laboratory. They find old Ensor dying slowly – he needs the power cells his son was trying to deliver implanted soon. Blake and Cally take Ensor and his invention, Orac, through the tunnels to reach the surface, but a skirmish with Travis slows progress and Ensor dies of shock en route to the surface. Avon and Vila arrive to save Blake and Cally from Travis, and teleport back to the Liberator while Servalan vows to Travis that his career as Space Commander is finished. On the Liberator, Orac is activated and the crew discovers that Orac is actually an incredibly advanced computer capable of making short-term predictions. When asked to do so, Orac projects an image of the Liberator being destroyed in a huge fireball onto the screen…
