MILLER (Miles Teller) and strait-laced pal Casey (Skylar Astin) arrive at the house of their pal Jeff Chang (Justin Chon), who is turning 21.
Birthday celebrations are put on hold because Jeff has an interview for medical school, organised by his controlling father Dr Chang (Francois Chau), the following morning.
After much persuading, Jeff agrees to accompany Miller and Casey out on the town for a couple of drinks before an early night.
Umpteen beers and shots later, the birthday boy is paralytic and Casey is smitten with a girl called Nicole (Sarah Wright).
Unfortunately, neither lad knows Jeff’s address so they embark on a madcap misadventure in search of inspiration, crossing paths with Nicole’s oafish jock boyfriend Randy (Jonathan Keltz).
21 And Over is a raucous and gleefully foul-mouthed comedy from the co-writers of the first Hangover film that bolts together set pieces into a fractured and debauched narrative.
