Col. Tigh's (Michael Hogan) imposition of martial law threatens to split the crew and the fleet. He's thrown Chief Tyrol (Aaron Douglas) 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 (Kate Vernon), 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 (Jamie Bamber) schemes to free President Roslin (Mary McDonnell) to establish a democratic opposition. He makes a break for freedom with Roslin, while Roslin's close aide Billy (Paul Campbell) chooses to stay behind. Tigh threatens to shoot down the Raptor carrying Roslin away from the Galactica, but the 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 (Grace Park) love for Tyrol to intimidate her into revealing how many Cylons are lurking in the fleet. On Cylon-occupied Caprica, Kara (Katee Sackhoff) and Helo (Tahmoh Penikett) 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 (Michael Trucco) and Sue-Shaun (Tamara Lashley), 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.
