It all starts when Doug (Justin Bartha) decides to get married. His friends Phil (Bradley Cooper), Stu (Ed Helms), and Alan (Zach Galifianakis) decide to give him a bachelor party in crazy Las Vegas that he could not forget. Unfortunately the morning after their arrival, they awaken in their hotel suite with the worst hangover ever. No one remembers what happened in the past twelve hours. While the suite is destroyed, they find out they have replaced the groom for a tiger and a baby.
As Phil, Stu and Alan try to find Doug using only what little pieces of information they have at hand, they discover what they did the previous night. However, they are running out of time to find Doug before the wedding, and having to explain to Tracy (Sasha Barrese) why they are not back in Los Angeles.
First they find out Stu got hitched, to a sexy stripper/escort, Jade (Heather Graham) with child. Then they discover Phil was in the hospital, so they visit the doctor he saw for more information on what happened - this is when they find out they were drugged with roofies. Their misadventures with a Chinese guy, Mr. Chow (Ken Jeong), has to be the funniest yet dangerous situations in the entire movie. They think all they need is $80,000 and it will be all over, but to their luck, Chow has the wrong ‘Doug’.
I highly recommend this movie to anyone who wants a great laugh!
