The simple devices found in an average toolbox become cruel weapons of death in the hands of a psychotic killer preying on the residents of a Los Angeles apartment building. As the maniac murders the tenants with such tools as claw-hammers, screwdrivers, and power drills, you'll thrill to the creepy chills of this exploitation classic.
