The Devil's Advocates - an outlaw gang of Harley-riding hellions led by Adam (Stephen Oliver of "Motor Psycho" and "Peyton Place" fame) and his ol' lady Helen (D.J. Anderson) - troll the dusty highways of the American Southwest in search of the next great kick, whether it be sex, drugs, or violence. After dispatching a pair of rednecks unfriendly to their lifestyle, the Advocates run roughshod over a gas station before taking to the road again, where they encounter a cloistered sect of Satanic monks led by high priest One (Severn Darden). A mass-drugging, a ritual sacrifice, a topless snake-dance, and a scene-clearing fistfight ensue, but it's too late: the spell has been cast, and two shall become' Werewolves on Wheels!'
