Happy Birthday to Sarah! Turning twenty-six and divorcing Brandon - her high school sweetheart - on the same day. With all of her plans for the future out the window, she tries her best to be content in a small apartment with her two cats. As the months go by her best friends, Tanya and Jenny, start setting her up on blind dates. After enough bad experiences Sarah refuses to let either of them pick a man for her again. When Jenny sees an ad from a local travel agency - a chance to win a ten-day trip on a single's cruise - without thinking, or asking, she enters Sarah's name. Now Sarah is the winner of something she doesn't want. With an enormous amount of pressure from her friends to go and nothing to lose, she packs her bags. The night of her twenty-seventh Birthday she meets Gabriel, a man she learns has as much baggage as she does. They make a promise to help each other let go of the past and it doesn't take long before she lets him into her bed and her heart. Women start showing up dead, sad accidents may be to blame but Sarah finds out that some of the crew doesn't think that is the case. The scary part is that they bare a striking resemblance to her. Sarah really gets worried when she is the person to uncover the third body and it is definitely no accident after the security camera recording is looked at. The number of dead women keeps rising and to make matters worse the ship has stopped moving - broken-down in the middle of the Atlantic Ocean. Every time a woman is murdered Gabriel's whereabouts are in question. Sarah finds herself hopelessly lost at sea with a killer. She doesn't want to believe it but could it be the man she has fallen madly in love with is a killer? Could she be the next to die?
