The Liberator leaves the Milky Way galaxy in search of Star One. The coordinates lead them to a cold planet orbiting a white dwarf star on the edge of the galaxy, and getting there, the crew realize that they are on the route that anyone desiring to reach the nearest galaxy, Andromeda, would take. Star One turns out to have an underground base manned by conditioned engineers from the Federation who maintain an antimatter satellite minefield designed to keep someone or something out of the Milky Way. Blake and Cally are captured on the surface, but Blake discovers that Travis is expected to arrive and assumes that identity. Cally, in the meantime, plants bombs. Avon watches on the planet as Travis arrives, but Travis escapes when Avon is distracted by a woman who claims that everyone else on Star One is out to kill her. Avon finds that this is indeed true, because everyone but Lurena is in fact an alien in the shape of the engineers they killed. Star One’s defense barrier is designed to keep out a possible invasion from the Andromeda Galaxy – and that invasion force arrives on the Liberator’s detectors. Jenna uses Orac to warn Servalan of the impending danger while Travis seriously wounds Blake. Avon kills Travis and the rest of the aliens on Star One, but the damage has been done and the zone will be deactivated on schedule, allowing the Andromedans to invade. The nearest Federation vessels are hours away from Star One, and the Liberator, with Avon in command, remains to fight off the invasion…
