Unhinged (1982)

Get your slice from the reaper. Violence beyond reason, Victims beyond help.

Three pretty young college students get into a car wreck in a rainstorm on the way to a rock concert. They awaken in an old secluded mansion under the care of middle-aged spinster Marion Penrose and her man-hating mother. Before long, their stay in the mansion becomes a deadly game of cat-and-mouse as the two demented women attempt to pick off their house guests one by one.
