Former Baywatch lifeguard Eddie Kramer arrives and appeals to Mitch to investigate a rescue that resulted in a death on the beach, for with he has been blamed. Meanwhile, Garner and Ryan go on a stakeout to watch an alleged thief.

A deranged man, named Garth Youngblood, takes a fancy to Baywatch lifeguard Caroline Holden and makes many advances toward her. When Caroline resists, Garth captures her and locks her in a cage furnished like her apartment, while Mitch teams with fellow Baywatch lifeguards, Newman and Barnett, to help him and Garner look for Caroline.
