As Laura (Mary McDonnell) plans to boost morale by celebrating Adama's (Edward James Olmos) 40th year of service, the Admiral's world is thrown into turmoil by the appearance of a pilot he thought was dead. Three years ago, Lt. Daniel Novacek (Carl Lumbly) was believed to have been killed on a top-secret mission in Cylon territory under Adama's command. Now, after enduring three years in a Cylon prison, Novacek has escaped, stolen a Raider, and made his way to Galactica. His arrival forces Adama to confront his betrayal of one of his pilots and the possibility that his actions may have provoked the Cylon attack on the Colonies. While Tigh (Michael Hogan) stokes the conflict by telling Novacek of Adama's hand in his fate, Starbuck (Katee Sackhoff) uncovers evidence that suggests that Novacek's escape may not be what it appears to be.

When two highly successful professionals die after claiming to be haunted by hellhounds, Sam and Dean investigate a local bar and discover that it sits upon a site where a deal-making demon has been making people's dreams come true in exchange for their souls. Dean summons the demon to exorcise it but is horrified after it reveals the painful truth about his father's death and tempts Dean by offering him the one thing he wants more than anything--his father.

A team from Galactica boards the infected baseship and finds hundreds of dead and dying Cylons. It's an intelligence windfall. Adama (Edward James Olmos) orders the team to tap into the dying Hybrid and to return with the surviving Cylons. Adama sends Starbuck (Katee Sackhoff) in to interrogate them. The deal she offers the Cylons is simple: cooperate and you get the vaccine and live; resist and you die - forever. Simon (Rick Worthy) reveals that Baltar (James Callis) is helping the Cylons find earth and Lee (Jamie Bamber) gets an idea: if the virus is spread by resurrection, it may be possible to set a trap and use it to destroy the Cylon race. Helo (Tahmoh Penikett) is outraged - this is genocide, the extinction of his wife's race - but Adama and Laura (Mary McDonnell) take the idea seriously. Meanwhile, the Cylons hold Baltar responsible for the virus and are torturing him for more information. Number Six (Tricia Helfer) talks him through the pain, filling his mind first with pleasure and then with a warning. As Galactica's trap is sprung and the Cylons move in, Baltar must once again choose between his own people and his captors while Helo must decide how far his loyalties will go.

On Galactica, divisions begin to appear between those who remained on the ship during the Cylon occupation of New Caprica and those, like Starbuck (Katee Sackhoff) and Tigh (Michael Hogan), who suffered under the Cylon yoke on the planet's surface. Tigh spearheads the discontent, his faith in human loyalty shattered by the betrayals he experienced on New Caprica. Starbuck, unable to shake off the pain of her long Cylon imprisonment, falls into step with him. After Lee (Jamie Bamber) and Kat (Luciana Carro) fail to settle the simmering rebellion, Adama (Edward James Olmos) is forced to put his leadership on the line to hold Galactica together. Meanwhile, in the Cylon fleet, Baltar (James Callis) plays a slippery game with the Cylons in order to persuade them he's worth keeping alive. When a crisis hits the Cylon fleet and a base ship is infected with a deadly virus, Baltar must prove his worth by volunteering for a dangerous mission.
