Psycho/slasher/sex maniac stalks a young woman.

The young Doug Gerhardt is a slasher and a homicidal sex maniac. Gerhardt invades the home of housewife and mother Marian Wood. Having already killed a girl who turned him down, Gerhardt threatens to harm Marian and her children Jeff and Josh if they don't give in to him. A homicide detective is Marian's only hope for salvation.—Robert
