Allison Fowles, a beautiful seductive woman, murders a man named Steve by handcuffing him to the bottom rung of a ladder in a pool. The next day, she leaves the house with a suitcase full of money and a dead Steve in the backseat. While on the road, she is spotted by Drew, her ex-partner, who starts chasing her. Allison loses control over her car and ends up driving off the edge off a cliff. Mitch and Eddie are in the scarab and head for the rescue immediately after the car has hit the water. Allison is rescued by Mitch but Steve can not be resuscitated.
Unfortunately for Allison, the money can´t be brought back up until the next day. Therefore, she seduces Mitch and without him knowing it, she wants him to protect her from Drew. Mitch and Allison share a very passionate evening together. During the night, Drew breaks into the house. Mitch starts fighting with him but loses. Just when Drew is about to shoot Mitch, Allison shoots Drew instead, who dies immediately. Allison tells Mitch that Drew was her ex-husband.
Eddie, who has been suspicious all along, asks to see the coroner´s report for the drowned man. When he reads the report, he discovers that Steve died in chlorinated water, not saltwater. It turns out that Drew was Allison´s ex-partner and they stole the money from Steve. When Allison decided to keep all the money to herself, Drew wanted her dead. Mitch can´t believe it when he first finds out about the truth.
By this time, Allison is long gone on her sailing boat but Mitch follows her in the scarab and confronts her about everything. She confesses to him even as she pulls a gun at him but Mitch talks her out of shooting him. At that time, Eddie and Connors have arrived and Allison is arrested by Connors.
