The simple devices found in an average toolbox become cruel weapons of death in the hands of a psychotic, black-clad killer stalking the residents of a Los Angeles apartment building. As the unseen predator kidnaps a terrified teenage tenant (Pamelyn Ferdin), will the efforts of her brother (Nicholas Beauvy) to uncover the madman and his motives be enough?
