We've had chainsaws, we've had power drills. Now the murder weapon is both portable and easy to conceal (if you're wearing an overcoat). The mysterious killer in Sledgehammer has targeted a previously tranquil small town. His choice of victims? Why, beautiful young women who can't act, of course. After several local lovelies are bludgeoned to death with a sledgehammer, the authorities suspect foul play. ~ Hal Erickson, All Movie Guide
