The wolf pack is back.  The trailer for 'The Hangover III' has the boys in trouble once again. Bradley Cooper, Ed Helms, Zach Galifianakis, Justin Bartha and Ken Jeong are back.  This time, trouble arises when the guys take a road trip to get Allen (Zach Galifianakis) professional help after his father dies.  John Goodman captures the guys in an attempt to re-coup money stolen from him by Chow (Ken Jeong).

The Hangover III hits theaters May 24th.
