This feature-length movie is a re-edited version of the first few episodes of the TV series. The story line concerns a spaceship full of survivors of a doomed planet who are headed to the Earth. Led by Commander Adama (Lorne Greene), they encounter villainous robots, threatening their journey to find Earth.
The number One Cylon brothers Cavil organize a massive coordinate simultaneous attack to destroy the twelve colonies, but it fails to wipe out human life or break the human spirit.
The story of how the Twelve Colonies of Man are destroyed after a 1000 year war with the evil Cylon Empire. Through deceit, the Cylons are able to destroy the Colonies' entire fleet, except for the Battlestar Galactica, captained by Commander Adama. Adama gathers up the few remaining humans left on all the twelve worlds and embarks on a journey to find the mythical planet Earth, the supposed thirteenth colony of Mankind, lost millennia ago when humans first left the motherworld Kobol. With food and fuel running out, the fleet heads for an ore planet, Carillon, hoping to get what they need.
The film takes place in the midst of the first Cylon war. As the battle between humans and their creation, the sentient robotic Cylons, rages across the twelve colonial worlds, gifted fighter pilot William Adama (Luke Pasqualino) finds himself assigned to one of the most powerful Battlestars in the Colonial fleet: the Galactica. Full of ambition and hungry for action, Adama quickly finds himself at odds with his co-pilot, battle-weary officer Coker Fasjovik (Ben Cotton). With only 47 days left in his tour of duty, Coker desires an end to battle as much as Adama craves its onset.
