When Lucy’s parents gift her and Max with a honeymoon cruise, she has one goal—improve their sex life. After three weeks of marriage and no orgasm, she begins to rue the fact that she was a virgin on their wedding night. By the third day on the beautiful Caribbean Sea, nothing has changed. Tearful and frustrated, she wishes on a star, asking that Max understand how to please her, and she know how to pleasure him.The next morning is a mind-blowing shock. She is in Max’s body and he is in hers. After a moment of panic, they decide they may as well make the best of it. Spending five days in each other’s body, joining a he-man contest, topless sunbathing, doing Texas-hold-em, dealing with curious friends, and playing out mutual sexual fantasies they create a whole new meaning to the term “love boat”.
