Battlestar Galactica

Humanity lived on twelve colony worlds in a far distant star system. They fought a thousand-year war with the Cylons, war robots created by a reptilian race which expired long ago. Having never been commanded to cease fire, these war robots continuously waged war against the colonials. Mankind was defeated in a sneak attack on their homeworlds conceived by these robotic servants, now referred to as Cylons, and carried out with the help of Baltar. Protected by the last surviving warship, a Battlestar called Galactica, the survivors fled in any ship that could fly. The commander of the Galactica, Commander Adama, led this "rag-tag fugitive fleet" in search of a new home on a legendary planet called Earth.
