 In a distant galaxy, twelve planets bearing tribes of the race known as Man have been at war with an alien cyborg race, the Cylon empire, for a millenium. In the measurements used by the Twelve Colonies it is the Yahren 7341, and a treaty of peace is to be signed - a treaty that proves to be a ruse for the largest assault in the history of galactic warfare. With their defending warships destroyed and their homeworld annihilated, the Twelve Tribes gather to their one remaining warship, a battlestar named the Galactica, boarding every assorted star vehicle that will carry them, as their leader, Commander Adama, seeks out the one planet that will protect Man from the predation of the Cylon Empire - a planet called Earth. As their journey proceeds this Fugitive Fleet is closely pursued by forces of the Cylon Empire under the command of human traitor Baltar.
