The Hangover Part II

Stu is getting married, and along with Doug, Phil, and his soon-to-be brother-in-law Teddy, he regretfully invites Alan to Thailand for the wedding. After a quiet night on the beach drinking beer and toasting marshmallows by the campfire, Stu, Alan, and Phil wake up in a seedy apartment in Bangkok. Doug is back at the resort, but Teddy is missing, there's a monkey and a severed finger, Alan's head is shaved, Stu has a tattoo on his face, and they can't remember anything. The Wolf-Pack retrace their steps through strip clubs, tattoo parlors, and cocaine-dealing monkeys on the streets of Bangkok to try to find Teddy before the wedding.
