From the writers of The Hangover comes a reckless and raunchy comedy 21 years in the making! On the day before a critical med school interview, straight-A college student Jeff Chang (Justin Chong, Twilight) gets a surprise visit from his two best buds (Skylar Astin, Pitch Perfect and Miles Teller, Project X) to celebrate his 21st birthday.
In no mood to party, Jeff finally agrees to a single drink, which quickly leads to an over-the-top, out-of-control night filled with epic beer pong, smoking hot coeds...and one angry buffalo. Can Jeff's friends get their plastered pal cleaned up in time for his morning appointment? It's worth a shot!
