A Federation installation on the planet Albian is taken by rebels as Blake arrives, but before dying, the last Federation officer activates a mechanism that will destroy all life on the planet, but leave the Federation bases and other structures intact. Avon and Del Grant teleport to the ice cap to deactivate the bomb, but while there, the only thing Avon can think of is the death of his lover, Anna Grant – and the only thing on Del Grant’s mind is why Avon allowed his sister to die. Meanwhile, Blake finds a Federation officer called Provine and interrogates him: Blake wants to know where the real Central Control is located. Before dying, Provine tells Blake that Control is now called Star One, and only a man known as Docholli knows where it is.
