When aliens invade the Wild West, a condemned outlaw fights back with everything he's got. The noose tightening around his neck, Sam Phoenix (James Marsters) prepares to meet his maker. Sam gets an unanticipated reprieve, however, when an evil insectoid strolls right into town square and sends everyone running. When the townspeople become the prey in an interstellar hunt, Sam vows to turn the tables on the extraterrestrial predators.
