Cameron Diaz and Ashton Kutcher star as strangers who wake up a married couple after a crazy night in Las Vegas in director Tom Vaughn's (STARTER FOR 10) film. Joy (Diaz) is the type of woman who makes plans to make plans. She's expecting a marriage proposal, but her live-in boyfriend, Mason (Jason Sudeikis), has other ideas. When he dumps her, Joy heads to Vegas to forget her troubles with her friend Tipper (Lake Bell) and discovers her fun, spontaneous side. Unfortunately, she also wakes up with recently unemployed Jack (Kutcher) as her husband. The two quickly decide to divorce, but the plot thickens when Jack wins a $3 million slot jackpot using Joy's quarter. Since neither one of them wants to give up the cash, they each try to drive the other to file for divorce and give up the bounty. But love has a funny way of appearing when you least expect it, and in acting their worst, Joy and Jack actually bring out the best in each other. Diaz and Kutcher have excellent onscreen chemistry and make a very photogenic couple. Treat Williams stars as Jack's difficult-to-please father, while Rob Corddry is Jack's best friend, Hater. Queen Latifah and Dennis Miller appear briefly as a marriage counsellor and divorce court judge, respectively. The Vegas scenes are flashy and fun,just like Sin City--and the settings for the New York City scenes differentiate nicely between Joy's organized, structured life and Jack's less serious, happy-go-lucky attitude.

Set in Sin City, story revolves around two people who discover they've gotten married following a night of debauchery, with one of them winning a huge jackpot after playing the other's quarter. The unhappy pair try to undermine each other and get their hands on the money -- falling in love along the way.
