Two days before his wedding, Doug drives to Las Vegas with his best buddies Phil and Stu and his future brother-in-law Alan, for a blow-out bachelor party they vow they'll never forget. When the three groomsmen wake up the next morning with pounding headaches, they can't remember a thing. Their luxury hotel suite is beyond trashed and the groom is nowhere to be found. With no clue about what happened and little time to spare, the trio must attempt to retrace their bad decisions from the night before in order to figure out where things went wrong in the hopes of finding Doug and getting him back to L.A. in time for his wedding. The more they begin to uncover, the more they realise just how much trouble they're really in!
