Jim (Jason Biggs) proposes to Michelle (Alyson Hannigan). Hoping to make the wedding day as special as possible for his bride, Jim enlists the help of his friends Finch (Eddie Kaye Thomas), Kevin (Thomas Ian Nicholas), and the always obnoxious Stifler (Seann William Scott) to help him convince a dressmaker to create the perfect gown, make a good impression on his future in-laws, and assist him in getting out of the embarrassing situations in which he so often seems to find himself. Stifler and Finch battle for the attention of Michelle's younger sister Cadence (January Jones), Jim's Grandmother objects to the wedding because Michelle is not Jewish, and Stiffler's poorly timed surprise bachelor party are just some of the obstacles that must be overcome before the happy event can transpire. Music video director Jesse Dylan ('How High') helms from the adaptation of the characters by Adam Herz.
