When billionaire mogul Gerald Hawthorne dies, he leaves behind an ultimatum for his son Ethan: in order to get the portion of his allotted inheritance, he must marry the woman who had taken care of him in his final days, Nurse Harmony Rhoades. Instead of getting angry, Ethan makes a deal with Harmony, one that will help him get around his father's contract. All seems to be going well until Ethan suffers a car accident that causes him to lose the last five years of his memory, which includes both Harmony and their deal. Chaos and fireworks ensue as Harmony finds herself playing the role of wife, hoping that Ethan recovers before she has to tell too many lies.
