In The Hangover 4 (2025), the Wolfpack reunites for one last “harmless” celebration—this time for Alan’s surprise engagement in Tokyo. Determined to prove he’s matured, Alan (Zach Galifianakis) insists on a quiet bachelor weekend, with Phil (Bradley Cooper) and Stu (Ed Helms) reluctantly agreeing. But when a mysterious drink at a karaoke bar sends the night spiraling out of control, they wake up in a back alley with no wallets, no pᴀssports, and no memory—again.
Worse, Alan’s bride-to-be has vanished, and the only clue is a bizarre video message involving a stolen samurai sword, a panda costume, and a legendary underground gambler who wants something back.
As they stumble through neon-lit chaos, backroom deals, and a run-in with Mr. Chow—who may or may not be their only hope—the Wolfpack must survive one last misadventure that makes Vegas look like child’s play.
The Hangover 4 is a wild, unpredictable ride full of hysterical moments, heartfelt surprises, and the ultimate reminder that with these guys… nothing ever goes according to plan.
