Emma (Anne Hathaway) and Liv (Kate Hudson) are life-long best friends. They do everything together. They even get engaged at the same time. Both girls have spent their entire lives dreaming of getting married at the Plaza Hotel in New York City. They even hire the same wedding planner, Marion St. Claire (Candice Bergin). Unfortunately, there is a clerical error that results in both weddings being scheduled on the same day. Neither is willing to reschedule, and both reject a joint wedding. The women quickly descend from best friends to strained acquaintances, and eventually declare all-out war on each other, as each woman's desire to have the perfect wedding consumes her, destroying a friendship that took years to build. Things go quickly from bad to worse at a joint engagement party, when Liv learns that Emma has already announced the wedding, and the date, to all of their friends. From that point, the former best friends engage in a series of pranks on one another, each trying to sabotage the other woman's big day. Their fighting causes strain on each woman's relationship with her fiance, leading to additional conflict. As the relationship between Liv and Emma devolves, each wedding hits additional road blocks - neither of them now has a maid of honor. Their mutual friends refuse to choose sides, meaning that each of them is forced to ask someone who is not a close friend to stand beside her. The two clearly miss each other, but their pride stands in the way of reconciliation. Finally, the big day arrives. Each woman has realized her mistake. They are appear to be close to an apology when Liv's assistant airs a video of Emma on spring break at her wedding. Liv had previously reconsidered the prank and cancelled it. Emma is so enraged, she attacks Liv as she is walking down the aisle. The resultant fight leads Emma to break up with her fiance after he insults Liv. The woman make up, and Emma walks Liv down the aisle.
