Jake (Tatum) is deeply in love with his girlfriend and ready to propose — until he runs into his high school flame (Rosario Dawson) for the first time in years. Jake's friend Cully (Chris Pratt) 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 back to his old ways instead. Meanwhile, longtime rivals Marty (Justin Long) and A.J (Max Minghella) 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 (Oscar Isaac) is now a rock star, but is still too shy to talk to his high school crush.
