Event Year: 2004

Ellen escapes from Cavil only to face a momentous choice regarding the 13th Tribe and the Final Five Cylons.

As Sam Anders recovers from his head injury onboard the Galactica, he begins to remember events from ancient Earth. The Final Cylon struggles with the fallout from the Final Five's former plans. One of the humanoid Cylons vows to get revenge for being created in the image of Man. Tyrol informs Admiral Adama about the extensive structural damage on the Galactica.

President Roslin faces off against Tom Zarek and Lt. Gaeta as they try to take control of the Colonial fleet. Both the alliance with the rebel Cylons and Adama's life are at stake.

Loyalties are made clear when Gaeta orchestrates a coup d'état of the Adama regime. Both prisoners and lives are taken as many of the fed up people work to take over Galactica.
