In a distant galaxy, after most of humanity is destroyed by a race of intelligent machines invented to serve humans known as Cylons, a few thousand survivors including a portion of the military escape in a fleet of ships led by the Battlestar Galactica. Under President Laura Roslin and Commander Bill Adama, the humans attempt to escape destruction by the Cylons and follow the words of an ancient prophecy guiding them to a new planet they call Earth. Along the way, a Cylon Civil War breaks out and some of the Cylons end up aligning themselves with humans while a number of humans are revealed to be unwitting Cylon sleeper agents.
