Decimated by a Cylon attack, the last surviving members of the human race escape their ruined planet and head for sanctuary on the lost planet Earth.

But Carillon, like much of the rest of the universe, is in the grip of the evil Cylon aggressors, leaving the crew to hatch a plan for a daring secret mission. The cast includes Lorne Greene, Richard Hatch and Dirk Benedict.
