The Cylon baby is finally born, leading to some political decisions being made. Meanwhile, the Cylons on Caprica contemplate life and humans when they meet up with a certain human from a previous episode. This story explores the Cylon world.

While Dr. Baltar is behind in the polls for the election and tries desperately to turn things around, Starbuck is planning a mission to rescue Anders from Caprica.

The group on Caprica is under fire by the Cylons, but suddenly they stop. With only one ship's votes to be counted, Roslin is way behind in the elections.

Now safely back in the fleet, those who managed to escape from New Caprica are seeking revenge against those they believe collaborated with the Cylons. Six of them, including Chief Tyrol and Col. Tigh, have formed the Circle and are acting as judge, jury and executioner. Those found guilty are blown out of an airlock. Lee Adama has noted that in the three days since everyone was reunited, 13 people have simply disappeared without a trace. The morale aboard the Galactica is not good with perceived collaborators being shunned by the others. Among those in that situation is Felix Gaeta who, as Gaius Baltar's Chief of Staff, is high on the Circle's list. As for Baltar is now being kept aboard a Cylon Basestar and his captors are deciding his fate as well.

The crew of Galactica makes a stop at the barren Algae planet.

The Cylons descend upon the re-supply mission as the Chief races to decipher the markings in the temple believed to hold The Eye of Jupiter, a sacred icon that is believed to contain a map to Earth.

When a Heavy-Raider manned by Leoben Conoy docks aboard the Demetrius, confrontations form between the crew over the possibility of a truce with Cylon rebels, while Starbuck puts her trust in an old enemy.

A vicious injury ends the mutiny attempt aboard the Demetrius, Kara leads her crew to the Cylon rebel's Basestar, and Roslin begins to understand Gaius Baltar's appeal to his followers. Meanwhile, Anders attempts to secretly find answers to his purpose as a member of the Final Five.
