Battlestar Galactica

Battlestar Galactica (abbreviated to BSG) is a TV series about a group of humans trying to find a new home after their old one was destroyed by Cylons. Cylons are robots created by humans to act like slaves. As a result they rebelled and nuked humanity. Now the 40,000 or so people who managed to survive join up in a "ragtag fleet of ships". Led by William Adama, the commander of the Galactica, they try to discover Earth.
