Friends John Beckwith (Owen Wilson) and Jeremy Grey (Vince Vaughn) are divorce mediators by day and womanizers by night. The pair are regular wedding crashers, doing so to meet beautiful women and ultimately have sex with them. When the pair are invited to a party by US Secretary of the Treasury William Cleary (Christopher Walken), John and Jeremy find themselves breaking their shallow sex rules and actually falling in love with the women they meet. The only problem? John is in love with Claire Cleary (Rachel McAdams), who is engaged to be married. Now, John and Jeremy have to conceal their past to land the women of their dreams.
