One of television's most celebrated dramas, "Battlestar Galactica" is the classic adventure of a ragtag fleet of humans, the sole survivors of a devastating nuclear attack by the robot cylons. Faced with an un-winnable battle against a deadly enemy, they are forced to flee under the protection of their one remaining warship, the outdated Battlestar Galactica. Pursued by the cylons - some of whom have now taken human form - Commander Adama (Edward James Olmos) and President Roslin (Mary McDonnell) lead these last remnants of humanity in search of a new home... a planet called Earth.
A Cylon, who calls himself Leobon, is discovered on one of the ships in the fleet. Commander Adama sends Kara to interrogate him--or, rather, it. The Cylon tells Kara that he planted a nuclear device on one of the ships.
