Following a disaster-filled trip to Thailand, Phil (Bradley Cooper), Stu (Ed Helms), Alan (Zack Galifianakis) & Doug (Justin Bartha) are back in the states and caught up in another set of misadventures. Also reprising their roles from The Hangover Part II (2011): Ken Jeong, Heather Graham & Jamie Chung.
