Evil monks! Severed demon hands! Satan erupting from a grave with a sword! What more do you need? When Samantha Eggar (THE BROOD) vists Stuart Whitman (NIGHT OF THE LEPUS) at an archeological dig, they unknowingly unleash . . . Demonoid. Naturally, Demonoid possesses the left hand of various humans and forces them to commit horrendous acts. The only way to get un-possessed: severe that hand. Praise Satan with this disco-infested fun-fest that features plenty of violence, an appearance by Russ Meyer discovery Haji (FASTER PUSSYCAT! KILL! KILL!), and inserts directed by 1980s trash guru Jim Wynorski (CHOPPING MALL).
