‘The Hangover’

Doug (Justin Bartha) drives to Las Vegas with his best buddies Phil and Stu (Bradley Cooper and Ed Helms) and his future brother-in-law Alan (Zach Galifianakis), for a blow-out bachelor party they vow they’ll never forget. But when the three groomsmen wake up the next morning, they can’t remember a thing. With no clue about what happened and little time to spare, the trio must find Doug and get him back to L.A. in time for his wedding.
