Michael goes to Vista Beach to investigate a string of robberies; the most recent hit is an art gallery owned by Marietta Mattheson and her niece Cindy. He learns the crimes occur when a local car club meets for street racing. Michael later runs into a gruff police detective, Chief Craig, who dislikes outsiders, especially ones who drive "suped-up" cars. Michael's prime suspect is Ron Prescott, Cindy's boyfriend, who has a police record and mysteriously skips town after a jewelry store is hit. Craig has another confrontation with Michael when he shows up at the gallery looking for Ron and harasses Cindy for his whereabouts.
