Plot

Bachelors and lifelong best friends, John Beckwith (Owen Wilson) and Jeremy Grey (Vince Vaughn) are partners at law in Washington D.C.. The friends frequently "crash" wedding parties to meet women, working from a set of rules taught to them by a past ‘crasher,’ Chazz. The duo always have cover stories for inquisitive guests and inevitably become the hit of every reception, to charm their way into bed with ladies at the wedding for a one night stand.

After a sequence of successful ‘crashes,’ Jeremy spots the wedding of the daughter of the Secretary of the Treasury William Cleary and his wife, Kathleen. After infiltrating the lavish event as brothers, John and Jeremy set their sights on two bridesmaids, also daughters of Secretary Cleary: Claire (Rachel McAdams) and Gloria Cleary (Isla Fisher). While Jeremy manages to make it on the beach with "stage-five clinger" and supposed virgin Gloria, John works on Claire. While talking afterwards, John is blocked by Claire's hotheaded and controlling Ivy League graduate boyfriend Zack, whom as the film progresses, isn't such a loyal boyfriend when he brags of his sexual conquests to his buddies behind Claire's back and seems to only want to marry Claire so he can advance his future political career by marrying into the family of powerful political figure. John convinces a resistant Jeremy to break the rules and accept an invitation to an extended weekend party at the Cleary family compound.
