Plot.
Scarred by repressed memories of his late mother, Michael overcomes his inner pain through the merciless slaughter of various women. His killing spree is characterized by a very peculiar modus operandi: he films each murder with his video camera and forces each victim to watch the film as they die. However, his dark side is penetrated via the romantic attentions of pretty neighbor Nola Carlisle (Vali Ashton), who seems intent on learning all she can about her handsome new friend.
