In this ensemble comedy, 10 Years follows a group of friends on the night of their high school reunion who, a decade later, still haven't quite grown up. Jake (Channing Tatum) is deeply in love with his girlfriend Jess (Jenna Dewan-Tatum) - until he runs into his old flame, Mary (Rosario Dawson). Cully (Chris Pratt) married his cheerleader girlfriend Sam (Ari Graynor), and has been looking forward to the reunion so he can finally apologize to all the classmates he bullied. However, a few too many drinks might get in the way of his good intentions. Longtime rivals Marty (Justin Long) and A.J. (Max Minghella) pick up right where they left off at graduation, vying to impress the hottest girl in class (Lynn Collins). Reeves (Oscar Isaac) graduated a band geek, but became a rock star, and knows tonight is his chance to finally talk to his secret crush (Kate Mara).
