The Hangover

Two days before his wedding, Doug and his three best friends head to Las Vegas for a party they'll never forget. But when the three groomsmen wake up the next morning with incredible headaches, they can't remember a thing. Their lavish hotel room is a mess and the groom-to-be is nowhere to be found. With no idea what happened and little time on their hands, the trio must try to remember all the bad decisions they made the night before in order to track down their missing friend and bring him back in time for his planned wedding in Los Angeles. But the more they discover, the more they realize how much trouble they've gotten themselves into.
