Watch What Happens in Vegas

What Happens in Vegas is a romantic comedy that stars Cameron Diaz, Ashton Kutcher, Lake Bell, Dennis Farina, Dennis Miller, Rob Corddry, Jason Sudeikis, Queen Latifah, Zach Galifianakis and Treat Williams. The film starts with stock broker Joy Ellis-McNally arriving at her surprise birthday party that she set up for her boyfriend only to have him break up with her. Heartbroken, she checks into a hotel room for a pre-planned vacation in Vegas. She finds that she has been double-booked with another hotel guest, Jack Fuller. He has just been fired from his job by his father.

After initial confrontation, Joy and Jack go out together for a night of partying in Vegas. Things go way too far, and the two impulsively get married. They have immediate remorse the next day and agree to have the marriage annulled. On the way out of the casino, Joy gives Jack some change to put into a slot machine, and he wins a multi-million dollar jackpot. Joy makes the claim that she is owed half of the money, as they are still officially married.

Upon returning back home, both Joy and Jay take great effort to undermine the other in order to stake their claim to the found money. They attempt to divorce but are told that they cannot do so until they attempt to cohabitate for at least six months. If they are unable to reconcile after that time, they can divorce and split the money. Neither accepts that challenge, and each works to outwit the other to claim the full prize. Joy works with some friends to get Jack to cheat on her, and Jack manipulates Joy’s ex-fiancé to get him to try and win her back.

They are forced to attend a marriage retreat when sparks start to truly fly between the two. The two go to a judge who will hear the arbitration case. Jack and Joy wonder what their future will hold.
