Awkward 14 y/o is not happy to be roped into spending summer vacation on a kind of trial run as a potential blended family as he and his mom (Toni Colette) join her asshat of a boyfriend (Steve Carrell) and his daughter at his beach home. But despite having no interest trying to fit in with the adults, who in general are even more juvenile than him, or with potential step-sis and other older teens who think him too dorky for words, he manages to meet up with some outsiders who help him gain confidence as the vacation drags on. Allison Janney, Amanda Peete, Maya Rundolph, Sam Rockford, AnnaSophie Robb co-star.
