It had been more than 40 years since the humans of the 12 Colonies of Kobol battled with the Cylons, the sentient robots that turned on their creators with deadly results. The robots had observed the armistice that ended the Cylon War, but the promised diplomatic relations between man and machine never materialized. The Cylons remained quiet for years and soon their threat was all but forgotten.

When the robot Cylons infiltrated the human defense system, they launched a surprise nuclear attack that decimated humanity and all of civilization, leaving a ragtag fleet of humans as the sole survivors. Faced with an un-winnable battle against a deadly enemy, they were forced to flee under the protection of their one remaining warship, the outdated Battlestar Galactica.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 and President Roslin lead these last remnants of humanity in search of a new home - a planet called Earth.
