The third installment in the American Pie franchise ties the knot between Jim (Jason Biggs) and Michelle (Alyson Hannigan). Though he encounters the usual fare of problems while planning a wedding, Jim's friends Finch (Eddie Kaye Thomas) and Kevin (Thomas Ian Nicholas) are there to give a hand. The trifecta gets disturbed once Steve 'Stifmeister' Stifler (Seann William Scott) shows up. Finch and Stifler become destracted by Michelle's younger sister, Cadence (Januayr Jones), who shows up to help with the wedding.
