During a wild vacation in Las Vegas, career woman Joy McNally and playboy Jack Fuller come to the sober realization that they have married each other after a night of drunken abandon. They are then compelled, for legal reasons, to live life as a couple for a limited period of time. At stake is a large amount of money.
Joy McNally’s meticulously organized life shatters when a drunken Vegas blackout leaves her legally bound to a charmingly reckless stranger. They must fake a honeymoon to secure a massive jackpot, forcing two opposites into a chaotic dance of forced intimacy and accidental affection.
