Bradley Cooper, Ed Helms and Zach Galifianakis wake up in their trashed Las Vegas hotel room after their best friend Justin Bartha's stag night

Bradley Cooper, Ed Helms and Zach Galifianakis wake up in their trashed Las Vegas hotel room after their best friend Justin Bartha’s stag night.

To their horror, they discover that they’ve lost him – and their memories of the night before – but managed to gain a tiger in the bathroom, a chicken on the loose and a baby in the closet!

The trio’s bleary-eyed efforts to find the groom, get him to the church on time with only five hours to spare and return the lost property is the making of a genuinely hilarious movie that includes a sweet hooker (Heather Graham), boxer Mike Tyson and a very angry Ken Jeong.
