Commander Shen is a formidable elite alien warrior, but also something of a short-sighted hot-head. When tasked with the mission of recapturing a hijacked deep space prison transport, Shen's impulsive cowboy-like actions give multiple alien convicts the chance they need to escape to a little blue planet called Earth. Now these very dangerous extraterrestrial fugitives are running around on Earth, doing God knows what to whoever they please, and no one can stop them, other than Shen, his android partner Seesix and a mysterious man in black known only as Mr. McGrath.
