Plot

The Wolfpack thought their days of epic disasters were behind them, but fate—and Alan—have other plans. When Alan Garner (Zach Galifianakis) inherits a jaw-dropping fortune from a mysterious relative he never knew existed, he insists on reuniting his best friends, Phil Wenneck (Bradley Cooper) and Stu Price (Ed Helms), for a “low-key” celebratory getaway to mark the occasion. Phil, now a seasoned high school teacher with a devilish streak, and Stu, a dentist still haunted by his Bangkok tattoo, reluctantly agree, hoping for a tame weekend of golf, cigars, and reminiscing about their wilder days. But as anyone familiar with the Wolfpack knows, nothing ever goes as planned.

The trip kicks off in Miami, where Alan’s newfound wealth attracts the wrong kind of attention: an eccentric crime syndicate led by a flamboyant kingpin, Viktor (Ken Jeong, reprising his chaotic energy from earlier films). After a night of champagne-fueled excess—complete with Alan’s attempt to “impress” the syndicate with his signature absurdity—the gang wakes up in a trashed yacht, missing a crucial piece of Alan’s inheritance: a rare artifact tied to his fortune. With no memory of the night before, a cryptic note from Viktor, and a pet iguana inexplicably wearing a diamond collar, the Wolfpack is thrust into a high-stakes scavenger hunt that spirals into international madness.

Their quest takes them from Miami’s glitzy underworld to the vibrant streets of Rio de Janeiro, where a carnival parade turns into a riotous chase involving a stolen float and a troupe of samba dancers. Just when they think they’ve hit rock bottom, a botched deal lands them stranded on a tropical island in the South Pacific, which harbors its own bizarre secrets: a reclusive billionaire (guest star Paul Rudd) with a penchant for hosting underground fight clubs, and a tribe of locals who mistake Alan for a prophesied “Bearded Oracle.” As the gang navigates iguana wrangling, makeshift raft-building, and Phil’s ill-fated attempt to charm the locals, they uncover clues about Alan’s relative, revealing a family secret that brings their friendship full circle.

Amid the chaos, old tensions resurface. Phil’s cavalier attitude clashes with Stu’s anxiety, while Alan’s childlike antics push everyone to their breaking point. Yet, as they face Viktor’s goons, double-crosses, and their own mistakes, the Wolfpack rediscovers what made them a family in the first place. The film weaves in nostalgic flashbacks to their Vegas days, including unseen moments from the original blackout, and delivers a series of jaw-dropping set pieces: a rooftop chase in Rio, a disastrous jet-ski escape, and Alan’s unforgettable karaoke performance of “Wrecking Ball” in a tiki bar showdown. The climax, set against the island’s volcanic cliffs, blends slapstick hilarity with a surprisingly poignant resolution, as each character confronts their fears and finds closure.

The Hangover 4 wraps up the saga with a mix of heart and hilarity, giving Phil, Stu, and Alan the send-off they deserve. A post-credits scene teases a potential spin-off, but for now, this is the Wolfpack’s final howl—a chaotic, emotional, and unforgettable goodbye.
