During the filming of a commercial out at sea, a woman falls of her jet ski and Matt has to rescue her. The woman turns out to be Jessie, the biker Matt met a year earlier (Episode 51: "Point Doom"). Mitch wants a lifeguard to be present during the filming and Matt is selected to go. Summer immediately becomes jealous because she knows about Matt and Jessie's previous meeting.
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.
