American Pie is the story of four Michigan high school seniors who make a pact to lose their virginity before graduation after a geeky classmate, Chuck Sherman (Chris Owen) claims to have done so at a party at Steve Stifler's (Seann William Scott) house.
Kevin Myers (Thomas Ian Nicholas), the initiator of the pact, tries to repair his relationship with his girlfriend Vicki (Tara Reid) after she has a serious fight with him at the party. Chris "Oz" Ostreicher (Chris Klein), who is on the school lacrosse team with Stifler, joins the jazz choir to pick up girls, as the girls there know little of his insensitive jock reputation. Paul Finch (Eddie Kaye Thomas), the mochaccino-drinking sophisticate, pays Vicki's friend Jessica (Natasha Lyonne) $200 to spread rumors of his sexual prowess, hoping that will increase his chances of success.
Jim Levenstein (Jason Biggs) pursues Nadia (Shannon Elizabeth), an exchange student from what is referred to as Czechoslovakia. She comes to his house to study with him, and has to change clothes there after ballet practice, so Stifler convinces Jim to set up a webcam so they can all watch her change. Jim runs over to Kevin's house to watch. Once he gets there, Nadia is seen on the computer discovering his pornography collection hiding in his dresser, and instead of finding it offensive, she begins looking through it while masturbating (this scene ranked #10 in the 100 Greatest Sexy Moments). Kevin urges Jim to run back home, saying this is his best opportunity. Jim arrives, and Nadia orders him to strip; meanwhile, it turns out that he had incorrectly addressed the e-mail to Kevin and Stifler, so instead of the link being sent to only his two friends, every mailbox in the school directory received the link; virtually the entire studentry is watching. As Jim slowly caresses her leg up to her genitals, he then climaxes prematurely. As Nadia is about to leave, he convinces her to stay, but upon seeing her full-frontally nude and touching her clean-shaven pubic area, he climaxes prematurely again, humiliating himself before the entire school. In desperation, Jim asks band geek Michelle Flaherty (Alyson Hannigan) to the senior prom, as she is apparently the only girl in the entire school who does not know what happened.
Finch, meanwhile, has his own troubles. Stifler, angry that a girl turned him down for the prom because she was holding out for Finch, puts a laxative into Finch's mochaccino. Unable to do his usual routine of heading home to use the toilet (Finch is paranoid about the lack of cleanliness in the school restrooms), Stifler directs him into the girls' restroom, for him to emerge before all of the other students, humiliated and left dateless.
At the prom, everything seems hopeless for the four boys until Vicky asks the girl that Sherman claimed to have bedded about her "first time". She gets even by proclaiming to the entire prom that she and Sherman did not have sex at Stifler's party, humiliating him. The revelation takes the pressure off of Jim, Kevin, Oz and Finch, and they head to the post-prom party with new hope.
At the party at Stifler's house after the prom, all four boys fulfill the pledge. Kevin and Vicki have sex in an upstairs bedroom, but the act is very awkward. Vicki breaks up with him afterward on the grounds that they will be too far apart in college, with him at Michigan and her at Ithaca. Oz confesses the pact to Heather (Mena Suvari), a girl from the glee club, and renounces it, saying that just being together with her made him a winner. They fall in love, begin a relationship, and end up making love on the porch. Having reformed, Oz never admits that they did. Finch strays downstairs to the recreation room where he meets Stifler's mom (Jennifer Coolidge). She is aroused by his maturity, and they have sex on a pool table. Stifler finds them together in the morning and faints. Jim and Michelle have sex after he finds out that she saw the "Nadia incident" after all. She accepted the date because of it, knowing he was a "sure thing", but she makes him wear two condoms to combat his earlier "problem" with Nadia. Jim is, to put it mildly, rather surprised by Michelle's behavior in bed. In the morning he wakes
up to find her gone, an inflatable dinosaur in her place. Essentially, she used him (which Jim thinks is "cool")
