Mitch is training for the annual Ironman competition and Garner documents everything on a videotape. Everyone tells Mitch to join the senior league, because he is old enough to qualify for it. But he wants to prove that he is still as good as he used to be and tortures himself during his training. It's obvious that he is going through a mid-life crisis.
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.
