'Hangover Part III' new trailer: Doug gets kidnapped (again)

The Wolfpack are back for one epic finale.

Before you watch the new trailer for The Hangover part III, a few things you should know about the third–and final–installment of director Todd Phillips' box-office shattering bromance comedy franchise.

1. Mr. Chow (Ken Jeong) stole a lot of money from a guy who looks like he could break a few bones, played by John Goodman.
2. Goodman's character hires Phil (Bradley Cooper), Stu (Ed Helms) and Alan (Zach Galifianakis) to hunt down Mr Chow for him. To motivate the rag-tag team, he kidnaps Doug (Justin Bartha). 
3. While on the lam, Mr. Chow seems to have developed some new “hobbies” (i.e. cock fighting and cocaine). 
4. Alan is just as crazy as ever, if not crazier because he appears to have stopped taking his meds.

You can watch the Wolfpack go out with a bang when The Hangover Part III opens nationwide May 24.
