A group of friends reunite at their high school reunion. A decade later, and they still haven't quite grown up. Jake is deeply in love with his girlfriend and ready to propose - until he runs into his high school flame for the first time in years. Jake's friend, Cully, married his cheerleader girlfriend and has been looking forward to the reunion so he can finally apologize to all the classmates he bullied in high school. However, after a few too many drinks, the jock-turned-family-man ends up reverting to his old ways. Meanwhile, longtime rivals Marty and A.J. spend the night picking up right where they left off, vying to impress the hottest girl in class. The famous one of the group, Reeves, is now a rock star but is still too shy to talk to his high school crush.
