With the Angels and Bosley still in Hawaii, the agency is hired by Congressman Sam Knight, whose daughter, Marti Lindsay, has gone missing, with her newlywed husband, David Lindsay, found unconscious in the surf on secluded Pacific Beach four days ago, he currently in the hospital in a coma, if and when he regains consciousness uncertain. Lt. Torres with the Oahu Police Department confirms that there have been a number of unsolved assaults on secluded beaches. As there has been no request for ransom, they can only conclude that Marti has been abducted by the same perpetrators that have been carrying out these assaults, her captors perhaps not knowing who she is. Against the advice provided to him, the Congressman decides to offer a cash reward for Marti's return, his action having unforeseen consequences. The Angels decide that their best course of action is to go undercover as lifeguards on some of these secluded beaches, Charlie unable to pull any strings for them to get one, two or three of the limited number of lifeguard certificates available.
