10 to Midnight

Warren Stacey (Gene Davis) is a young office equipment repairman who kills women after they reject his sexual advances. His attempts at flirting are always seen as "creepy" by women, resulting in frequent rejections.[4] His first victim is Betty (June Gilbert), an office worker of his acquaintance. He tracks her down to a wooded area, and observes her having sex with her boyfriend. He ambushes the couple, kills the boyfriend and then gives chase to the naked woman. He catches her and stabs her to death.
