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!
