On Caprica, the reincarnated Number Six (Tricia Helfer) and Sharon (Grace Park) are hailed as Heroes of the Cylon for the key roles they played in the near-destruction of the human race. But these are tortured heroes. Number Six's thoughts are haunted by Baltar (James Callis), just as she haunts his thoughts on Galactica. And Sharon has so fervently embraced her love for Tyrol (Aaron Douglas) and the fake human life the Cylons created for her undercover mission that the Cylon leadership D'Anna (Lucy Lawless) and Doral (Matthew Bennett) are thinking of "boxing" her (putting her consciousness into cold storage). Meanwhile, the human resistance under the leadership of Kara's lover, Samuel Anders (Michael Trucco) is preparing to strike a savage blow, however futile, against the Cylon occupation. On Galactica, the captive Sharon gives premature birth to Hera, the child she conceived with Helo (Tahmoh Penikett). As the infant fights for life, she becomes the focus of intrigue, as President Roslin (Mary M

Following a firefight with Cylon Centurions and the death of her spiritual advisor Elosha, President Roslin (Mary McDonnell) treks onward with her confederates in search of the Tomb of Athena. Heavy rain and Kobol's rugged terrain make the journey difficult for all except the tireless Sharon (Grace Park). Tom Zarek (Richard Hatch) again butts heads with Lee Adama (Jamie Bamber), inspiring Zarek's henchman Meier (James Remar) to consider drastic measures that will clear the path to power for his old friend. Meanwhile, aboard the Galactica, Gaius Baltar (James Callis) questions his sanity as Number Six (Tricia Helfer) toys with him, and Commander Adama (Edward James Olmos) mounts a rescue mission to Kobol. Adama enlists presidential aide Billy Keikeya (Paul Campbell) to join his quest for peace with the rebels. After discovering Elosha s grave on Kobol, the Galactica landing party continues its search and finally intercepts Roslin and her group. Putting aside old conflicts, Adams opens the door to peaceful

As the sun rises on Caprica, Starbuck (Katee Sackhoff) and Anders (Michael Trucco) discover that the Cylons have vanished. Brother Cavil declares it a miracle. But when they return to Galactica, the real reason for their survival become clear. Brother Cavil is a Cylon his double counseled Tyrol (Aaron Douglas) and he s here to deliver a message: The Heroes of the Cylon Number Six (Tricia Helfer) and Sharon (Grace Park) have persuaded the leadership that trying to destroy the humans was an error. From now on they will live apart, in peace. At the same time, voting continues in the presidential election. Laura (Mary McDonnell) approaches Baltar (James Callis) and proposes that, whoever wins, they agree that colonization of the newly discovered planet will wait for further study. When Baltar spurns her offer, she confronts him about Number Six and, when he remains unmoved, she instructs her aide to take steps to steal the election. The plot, however, is discovered and Laura and Adama must choose betwee

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 wa

Gaius Baltar (James Callis) believes the case against him is in tatters given the shattered credibility of key prosecution witnesses Colonel Tigh (Michael Hogan) and Laura Roslin (Mary McDonnell). The defense team of Romo Lampkin (Mark Sheppard) and Lee Adama (Jamie Bamber) is less confident after Gaeta (Alessandro Juliani) tells the court that he saw Baltar signing a death list on New Caprica. Lampkin's surprise motion for a mistrial leads him to call Lee to the stand, in a move that could incriminate Admiral Adama (Edward James Olmos) himself. Meanwhile, eerie coincidences are being experienced aboard Galactica. The sound of a familiar but untraceable melody haunts a several members of the fleet. President Roslin is also unnerved upon learning that her nocturnal dreams of the Kobol Opera House are shared by Sharon (Grace Park) and Caprica Six (Tricia Helfer). Whether a vision, dream or "projection," Roslin suspects it's the work of the mysterious Cylons known as the Final Five.
