A second full-length trailer for The Hangover Part III, starring Bradley Cooper, Zach Galifianakis and Ed Helms, has been released, shedding more light on the plot of this third and final installment in The Hangover franchise.

From the looks of it, Allan’s (Galifianakis) father (Jeffrey Tambor) has died, and Allan has stopped taking his medication. The “wolf pack” must hold an intervention for Allan and then take him to rehab. But on the way to rehab they are kidnapped by a menacing man (John Goodman) who claims that Leslie Chow (Ken Jeong) stole $21 million from him, and he wants Allan, Phil (Cooper) and Stu (Helms) to track Chow down, all the while taking Doug (Justin Bartha) as "insurance" until Chow is found.
