New York socialite Carly Hodge thinks she's kept her infidelity secret from her husband, Preston. She's wrong. On the pretext of celebrating her fortieth birthday, Preston takes Carly to the Bahamas on a sailboat. Under the night sky on the Little Bahama Bank, he serves her a romantic dinner and gives her the best sex of their nineteen-year marriage. Then he beats her, ties her to the mast of the boat, and blows the boat up while making his getaway.
Carly survives the murder attempt. Faking amnesia, she allows the world to believe she and her husband were victims of a boating accident in which he perished, but she knows he's hiding somewhere in the Bahamas and she's out for revenge.
