Cameron Diaz leads a knockout cast in this irreverent buddy comedy about love, lust and the laws of karma. When Carly (Diaz) learns that her boyfriend (Nikolaj Coster-Waldau) has a wife (Leslie Mann), the two women become unlikely friends. When he turns out to be an even bigger cheat than they knew, they make plans with yet another of his mistresses (Kate Upton) to teach him a lesson – or three!
