Two years after their wild bachelor party in Las Vegas, Phil, Stu, Alan, and Doug travel to Thailand for Stu's wedding. Determined to avoid another disastrous night, Stu plans a quiet pre-wedding brunch. However, things quickly spiral out of control when the group wakes up in a seedy Bangkok hotel room with no memory of the previous night.

With Stu's future brother-in-law missing and chaos unfolding across the city, the Wolfpack must retrace their steps through Bangkok's dangerous streets to piece together what happened. As clues emerge involving monks, gangsters, and a mysterious tattoo, the friends race against time to find the missing guest before the wedding begins.
