Some gang-members have sprayed their symbol on headquarters. The same gang also robs Hobie when he has sold some A & W soda on the beach. Meanwhile, Stephanie is upset because Mitch hasn't told her about the hiring of a new substitute lifeguard while Newmie is on vacation. But Mitch tells her she will like him. The substitute is named Carlos and he and Stephanie immediately fall for each other. They see the gang robbing Hobie and go there to help him. Carlos runs after them and Stephanie gets the impression that he knows the girl in the gang.
This long-running series follows the adventures of a team of lifeguards on the crowded beaches of Los Angeles County. Veteran lifeguard Mitch Buchannon watches over the younger lifeguards that come and go with each passing season as they keep the beaches safe for vacationers. Frequently he must take action to save them from the raging seas and from the raging tempers that sometimes flare up between the young guards in this stressful job.
