S01E02 Part 2

Overview

After forty years of armistice, the Cylons attack the Twelve Colonies of Kobol. Their strategy: a virus implanted into mankind's defense system. The former Battlestar Galactica, which is being adapted into a museum, is not connected with the defense system and becomes the only warship capable of fighting against the Cylons in the hopes of leading the survivors to planet 'Earth'.
