Battlestar Galactica

The Galactrica, a futuristic aircraft carrier the size of a small city, careens through a distant starfield followed by a convoy of bizarre space vehicles, all fleeing the destruction of the human race.
Led by Commander Adama, these survivors have started on a journey to a thirteenth sister colony in a distant galaxy star system - a planet called Earth. Battlestar Galactica follows these interstellar refugees and their battles with their enemy - the dreaded lizard-like Cylons.
