This romantic comedy starring Cameron Diaz and Ashton Kutcher is a bit like a night in Vegas: loud, flashy and difficult to recall the next day. Slacker and party animal Jack (Kutcher) is out to let off steam in "Sin City" when he meets Joy (Diaz), a control freak trying hard to let her hair down after being dumped. A few drinks later and they're saying "I do". But things get really complicated when he hits the jackpot on the casino floor - using her coin. A game of one-upmanship quickly grows tiresome as each party seeks to claim the cash, and the most ridiculous in a series of contrived twists sees a judge sentence the couple to "six months hard marriage". The two leads have good chemistry and at least Kutcher keeps the mugging to a minimum, but that doesn't make up for an empty hand in the wit and ingenuity stakes.

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.
