The Sinister Urge

The film revolves around a series of murders of young women. The opening scene features an unnamed blonde woman (Betty Boatner) running along a mountain road, wearing only her undergarments. She is clearly scared for her life. She enters a city park and manages to reach a telephone booth. Her attempt to escape her assailant ends in failure, when the man also reaches the booth. He quickly kills her and leaves her corpse next to a lake. The corpse is soon discovered by visitors of the park.<ref name="Craig">Craig (2009), p. 200-216</ref> The scene shifts to a police station, where Police Lieutenant Matt Carson (Kenne Duncan) receives a phone report on the latest murder. He instructs subordinate Officer Kline (Fred Mason) to gather information from the witnesses who called in the discovery of the body. Then he summons his associate Sergeant Randy Stone (Duke Moore) and they head out towards the crime scene. They take note of the youthful appearance of the victim and suspect a connection to the "smut picture racket".<ref name="Craig">Craig (2009), p. 200-216</ref>
