Roscoe is a hot rod-riding zombie, an undead gearhead and defender of the small Southern California town of La Cruz in the Freewheeling Fifties. Along with his friends, college age witch Betty Bright, Zoot Suiter shaman Angel Rey, and former bank robber Wooster Stokes, Roscoe takes on monsters and magic with motors and mayhem.

But now, a simple government job to capture a runaway rocket scientist and a stolen experimental flying saucer sends Roscoe and his friends into their toughest job yet. They’ll go up against ruthless Las Vegas gangsters, an insane alien-worshipping cult, a top secret government agency devoted to stealth and slaughter, and bizarre creatures from other worlds in their cross country mission to rescue a captured alien being and save the world from extraterrestrial destruction and an impending apocalypse.
