Battlestar Galactica: 1x2

Part 2

After forty years of armistice, the Cylons attacks the Twelve Colonies of Kobol. Their strategy: a virus implanted into the mankind 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’.
