Liz, a paralegal from New York, has all but resigned herself to a life of mediocrity. When she reluctantly agrees to attend a bachelorette party in Las Vegas, she decides that her life is ripe for change, and she breaks her engagement to her lackluster fiance, Peter, who seems more interested in video games than becoming an adult. Ben, a screenwriter from California, is about to change his own life by selling his screenplay at a meeting with a business executive in Las Vegas. Moments before he departs for the meeting, his wife blindsides him with divorce papers. The two meet at a chance encounter in Las Vegas, and pretend to be married to each other to avoid the advances of other would-be suitors; this farce snowballs into another evening, and finally they are faced with the task of acting as a married couple for the entire weekend and have to admit that they might be developing feelings for each other. But are their feelings based in truth or have they just gotten caught up in the theatrics of the weekend?
