In the summer of 1999, four small-town Michigan boys began a quest to lose their virginity. In the ensuing years, Jim (Jason Biggs) has married Michelle (Alyson Hannigan), though Kevin (Thomas Ian Nicholas) has left Vicky (Tara Reid). Oz (Chris Klein) has grown apart from Heather (Mena Suvari), but Finch still has the hots for Stiffler's (Seann William Scott) mom (Jennifer Coolidge). These lifelong friends have come home to reminisce about -- and become inspired by -- their former teen selves.
