When Robert Knight (Bernie White) is placed in a mental institution by his money-hungry relatives, he escapes and seeks vengeance. Hardly an innocent victim, Robert really is a crazed killer, so none of the characters evoke much sympathy. His main targets are his Uncle Charles (Dick Sargent) and Aunt Joanne (Marilyn Hassett).This dysfunctional bunch makes the Manson family look like Ozzie and Harriet as they resort to murder and cannibalism.
