When the 12 Colonies of Man are all but wiped out by a cybernetic race called the Cylons, Commander Adama and the Battlestar Galactica lead a ragtag human fleet of survivors in search of a mythical planet called Earth! Lorne Greene, Richard Hatch and Dirk Benedict star in the classic TV space opera — one of the most lavish and special effects-intensive series ever telecast.

Note : Battlestar Galactica is the correct spelling, not Battlestar Gallactica as 50% of the web searches reveal.
