Col. Tigh's imposition of martial law threatens to split the crew and the fleet. He's thrown Chief Tyrol into the brig on suspicion of being a Cylon and his dismissal of the Quorum has provoked the other ships to refuse to send fuel and other supplies to the Galactica. His judgment blurred by drink and the goading of his ambitious wife, Ellen, Tigh sends armed troops to one of the ships to take supplies by force, a move that ends in disaster when civilians are killed.
Amid this chaos, Lee schemes to free President Roslin to establish a democratic opposition. He makes a break for freedom with Roslin, while Roslin's close aide Billy chooses to stay behind. Tigh threatens to shoot down the Raptor carrying Roslin away from the Galactica, but he can't bring himself to kill his friend's only surviving son, and Lee and Roslin escape into the fleet at large.
Meanwhile, Baltar uses Sharon's love for Tyrol to intimidate her into revealing how many Cylons are lurking in the fleet.
On Cylon-occupied Caprica, Kara and Helo find themselves in a standoff against other humans. Cooler heads prevail, and the pilots meet their new allies: a group of 53 survivors, led by Anders and Sue-Shaun, members of a professional pyramid team that survived the nuclear holocaust because they were training in the mountains. Kara enlists their help in her mission to get off Caprica.
