Emma (Anne Hathaway) and Liv (Kate Hudson) are best friends who have planned every detail of their weddings since childhood. At the top of their bridal “must have” list: a ceremony at New York’s ultimate bridal destination, the Plaza Hotel. Now, at age 26, they’re both about to get married, they’re about to realize their dreams, and they’re about to live happily ever after. Or maybe not. When a clerical error causes a clash in wedding dates–they’re now to be married on the same day!–Liv, Emma and their lifelong friendship are put to the ultimate test. Liv, a successful lawyer who is used to getting what she wants, including the perfect job and the perfect man, won’t settle for anything less than the perfect wedding she has dreamed of for years. Emma, a schoolteacher who has always been good at taking care of others, but not so much in looking after herself, discovers her inner Bridezilla and comes out swinging when her own dream wedding is imperiled. Now, the two best friends who’d do anything for each other find themselves in a no-holds-barred, take-no-prisoners struggle that threatens to erupt into all-out war. The girls both attempt to “sabotage” the other’s wedding, including Liv making Emma’s tan go bright red, and Emma sending Liv a “treat” of chocolate cookies in order to make her fat,so she can’t fit inside her dress, showing up at one’s bachelorette party and dancing suggestively with male strippers, dying one’s hair blue, which ends up ruining their relationship. These shenanigans go on, then when the wedding day comes, Liv earlier gave her assistant a DVD of Emma dancing drunkenly during a Spring Break bash, but gave him the original DVD and told him to change it back, because she was finished with the fighting. He ends up ignoring her request saying, “You’ll thank me one day.” The DVD shows up at Emma’s wedding as she walks down the aisle, making Emma angrily storm into Liv’s wedding and tackle Liv. Liv bursts into tears and apologizes for ruining Emma’s big day. Emma’s boyfriend announces that Emma isn’t the girl he thought he was marrying. Emma then tells him that he is in love with the Emma he met 10 years ago, not the Emma that she is now. She realizes that the guy she was going to marry isn’t the right guy for her, and calls off the wedding. They share a hug as she takes off the ring, and he walks out of the hall. Emma and Liv make up and the wedding is restarted, this time having Emma give away Liv. During the wedding dance after Liv gets married, Emma is asked to dance by Nate (Bryan Greenberg), Liv’s brother, and the two hit it off. As the film ends, Liv and Emma catch up about a year later: Emma is now married to Nate and the past is forgotten. Both ladies announce that they are pregnant, and they learn that both babies are due on the same day. This time instead of arguing, both women rejoice at being parents for the first time.
