Set in the west and southwest of the United States, this frantically-paced social satire with a science fiction twist is the story of Taz, a nutty visionary, who has temporarily misplaced the wizened dried-out Brainstem he found in a mysterious subterranean world — which he believes is the key to immortality. Three rebellious punks, Sean, Head and Billy Dork, unknowingly steal it in the course of a convenience store robbery believing it to be a stick of beef jerky. Newlyweds Bruce and Sheila have the misfortune to stumble into the confrontation between Taz and the Punks: The punks kidnap Sheila as a hostage. Taz kidnaps Bruce as his hostage; the bizarre chase is on! The two “teams” race across a landscape of identical convenience stores, housing developments, and rampant consumerism.
