Blue Shift is the story of Shen, a formidable alien law officer who is something of a short-sighted hot-head. When tasked with recapturing a hijacked deep-space prison ship, Shen's impulsive cowboy-like actions give several alien convicts the chance they need to escape to an odd blue planet Earth. Now these dangerous extraterrestrial fugitives are running around on Earth, doing whatever to whoever they please, and no one can stop them, except for Shen, his robotic partner Seesix and a mysterious man in black known only as Mr. McGrath.
