This movie is similar to the 1930s Myrna Loy classic Thirteen Women, which is considered by some to be the very first slasher movie. It is about a woman who is rejected from a sorority and gets revenge by causing the murders of all of its members.
Lois Kelso Hunt's performance is entirely dubbed. Her voice was deemed not "scary" enough for the role. In the Special Edition DVD from Liberation Entertainment the film's director Mark Rosman comments that he believed that she had the right look for the part but ideally he would have preferred a huskier voice, with Lois's voice being more high pitched than he would have liked.
The gory payoffs to the murder scenes were added after the shoot and filmed in the backyard of director Mark Rosman's parents.
The film was inspired by the Italian horror films of Mario Bava and Henri-Georges Clouzot's classic thriller "Diabolique" (Diabolique (1955)).
