Suggest a movie title for the following movie plot: We open with a narration and a sweeping view of a river wash. A couple, Pat Wheeler (Grady Vaughn) and his girlfriend, Liz Humphries (Yolanda Salas) are sitting in his car when something pushes the car over and down a ravine and into the wash. A giant claw fills the screen and credits roll.A group of teens are dancing at a soda shop. Gordy (Don Flournoy) and his girlfriend, Jennie (Jan McLendon) pull up outside in Gordy's roadster. Chase Winstead (Don Sullivan) and his girlfriend Lisa (Lisa Simone) arrive in Chase's roadster. Chase inquires about Pat and Liz, and when told their car may have broken down, Chase immediately challenges that by saying, "not in his heap, I worked on it myself." Lisa works for the Wheeler family. She is an exchange student from France and Mr. Wheeler is her sponsor. She tells everyone Pat didn't come home for dinner and his father was very upset. Old Man Harris (Shug Fisher) arrives in his 1932 Ford. Chase wants to buy his car but Harris is not interested in selling. The gang of kids leaves for the drive in.The Sheriff (Fred Graham) pulls up to the large Wheeler home. He meets with Mr. Wheeler (Bob Thompson) regarding his missing son, Pat. Wheeler tells the sheriff that both his son and Pat's girlfriend didn't come home last night. The sheriff infers they may have eloped. Wheeler blames Chase; he thinks Chase has too much influence over his son and the rest of the kids in town. The Sheriff reminds Wheeler that Chase is a good kid and works hard after his Dad died "on one of your drill rigs." The Sheriff stops at Compton's Garage to talk to Chase. He thinks Chase may know where Pat and Liz have gone. Chase tells him he doesn't know, but dismisses the elopement theory. The final stop by the Sheriff is the Humphries' farm. He meets with Ed Humphries (Howard Ware) and his wife Agatha (Stormy Meadows) about their missing daughter, Liz. They have no idea where she is, but are more gracious and understanding of the Sheriff's challenge than Mr. Wheeler. On his way out he bumps into Harris....
