Mother, May I Sleep with Danger? 1996

A young woman, Bryn Erin, ends her relationship with her boyfriend, Ivan Sergei Billy, after kissing their mutual friend Lochlyn Munro Kevin and deciding to pursue a relationship with him. Enraged, Billy bludgeons Erin to death and conceals the crime.

Some time later, Laurel Tori Spelling starts a relationship with Billy, who has assumed Kevin’s identity. He becomes overly attached, but she is drawn to his intense affection; when he behaves inappropriately, she accepts his apologetic romantic gestures. After Laurel is introduced to her mother, Jessica, Billy becomes increasingly more aggressive and jealous. He convinces Laurel to cut and bleach her hair, both to incense Jessica and to make Laurel resemble Erin. Jessica suspects “Kevin” is not who he claims to be.

To protect his assumed identity, Billy murders Kevin, who had been out of town. He convinces Laurel to live with him in an isolated cabin with no telephone. After she discovers he is not arranging installation of a phone line as he had claimed, she confronts him and decides to move out. He drugs and abducts her, driving her car to her family’s cabin. Meanwhile, Jessica uncovers Billy’s lies and contacts the police; when she recognizes a missing persons photograph of Erin, having also seen it in Billy’s home, the police deduce that Billy has assumed Kevin’s identity. Billy calls AAA when Laurel’s car breaks down, alerting Jessica to their location. Laurel wakes up and locks herself in the cabin, but Billy breaks in with an axe. Laurel flees onto a lake in a rowboat as Jessica arrives; the women fight Billy on and around the lake. Distracting Billy by pretending to side with him, Laurel knocks him into the water with an oar; Laurel and Jessica embrace and Billy vanishes.

Elsewhere, a young woman resembling Erin and Laurel excitedly makes plans with her new boyfriend, Preston, who is Billy with another new identity.
