John Beckwith and Jeremy Grey are Washington D.C. divorce mediators who crash weddings to meet and have sex with women. At the end of a season of successful crashes, Jeremy takes John to a wedding for the daughter of the U.S. Secretary of the Treasury, William Cleary. Once inside, the pair set their sights on Cleary's other daughters, Gloria and Claire. Jeremy ends up having sex with Gloria on a nearby beach during the reception. Gloria is possessive and quickly becomes obsessed with Jeremy, and Jeremy urges John to escape the reception with him. Meanwhile, John attempts to court Claire, the maid of honor, but is interrupted by her hotheaded boyfriend, Sack Lodge, who is unfaithful and disrespectful behind her back. When Gloria invites Jeremy and John to an extended weekend party at their family compound, John overrules Jeremy to accept and get closer to Claire.
