It seems that some people never learn, and only two short years after that fateful night in The Hangover (2009), the original Wolf Pack, Phil and Doug, along with the awkward fourth wheel, Alan, find themselves in exotic Thailand for Stu's wedding to charming Lauren. Next thing they know, the boys wake up in a seedy Bangkok hotel, and to make matters worse, there's no sign of Teddy, Lauren's brilliant sixteen-year-old brother. Of course, none of them can remember what has happened the night before. Now, apart from a severed ring finger, a tiny Capuchin monkey, and the team's nemesis, Leslie Chow, lying on the floor, the team is clueless. But, once more, time is against them, and before getting back to Stu and Lauren's wedding ceremony on time, last night's survivors must first piece together the fragments of yesterday's trail of destruction through the underbelly of the city. Can the amnesiac band decode the missing hours before it is too late?—Nick Riganas
