American Wedding

The curtain opens on a tender moment between Jim Levenstein (Jason Biggs) and Michelle Flaherty (Alyson Hannigan) as they celebrate their college graduation with a dinner date. The air is thick with anticipation, as Jim prepares to pop the question after three years of dating. However, fate has other plans, and a phone call from his dad interrupts the romantic moment, revealing that Jim had forgotten the engagement ring at home. As Jim tries to stall for time, Michelle misconstrues his intentions, thinking he wants to spice up their love life in public. She takes matters into her own hands, leaving Jim stunned as he frantically attempts to hide the situation from his dad's arrival. The ensuing chaos is nothing short of spectacular, with Jim's dignity taking a hit as he tries to salvage the proposal.

After the ordeal, Jim and Michelle head out for a night on the town with their friends Kevin (Thomas Ian Nicholas) and Finch (Eddie Kaye Thomas) to celebrate their engagement. As they let loose, it becomes clear that Michelle has a secret passion for dancing, while Jim's lack of rhythm makes him a laughingstock. The group quickly comes together to agree on one thing: Stifler (Seann William Scott) is not invited to the wedding and must be kept at bay. But Stifler, ever the troublemaker, drives by Jim's house, mistaking the engagement party for a graduation bash, and crashes the proceedings. His antics lead to a cake-covered catastrophe, with Jim finding himself in an awkward situation when Michelle's parents (Fred Willard and Deborah Rush) arrive.

As tensions rise, Stifler takes it upon himself to organize the bachelor party, much to Kevin and Finch's dismay. Despite being told he's not invited, Stifler volunteers for the task, determined to make Jim's final days of freedom unforgettable. Little do they know, however, that Stifler has a few tricks up his sleeve, setting the stage for a wild ride of debauchery and hilarity.

As the wedding day approaches, Jim's anxieties about the ceremony reaching catastrophic proportions. Michelle's parents are still fuming over the unfortunate canine incident, and she's quietly stewing in her own worries, unwilling to confide in Jim about her true desires for the big day. Meanwhile, he's oblivious to her concerns, fixated on the prospect of a disastrous dance-off that will leave him red-faced and embarrassed. Desperate for advice, Jim turns to his friends Kevin and Finch, who offer their assistance and vow to help him avoid a humiliating spectacle.

Seeking to rectify this situation, Kevin and Finch pay a visit to their old buddy Stifler, attempting to subtly convey the message that they won't be inviting him to the wedding. However, Jim decides to take matters into his own hands and pays Stifler a visit, hoping to explain the reasoning behind his exclusion. But things quickly spiral out of control as Stifler's ire is piqued, and he unleashes a tirade of rage, with his football teammates joining in, creating a cacophony of chaos.

As Jim struggles to contain his frustration, Stifler seizes the opportunity to whisper a tantalizing offer: he claims to possess hidden dance skills and offers to tutor Jim. Despite initial reservations, Jim agrees to take lessons from Stifler, and they embark on an unlikely mentorship. Meanwhile, Finch has been covertly surveilling Michelle, seeking insight into her wedding aspirations. His findings reveal that she's fixated on a specific designer dress, available only through one exclusive boutique in Chicago.

Armed with this knowledge, Jim assembles his entourage, including Stifler, and sets out to track down the elusive Leslie, the dressmaker responsible for Michelle's dream gown. They arrive in Chicago, but their initial attempts to locate Leslie are thwarted when they find her absent from the store. A sympathetic colleague agrees to provide them with a list of bars where they might find Leslie, prompting the group to split up and cover more ground.

Stifler, ever the troublemaker, ends up at a gay bar, where he gets into an altercation with a formidable figure known only as Bear, who happens to be acquainted with Leslie. Bear rebuffs their pleas for assistance, sending Jim's hopes of finding the dress maker crashing. Just when all seems lost, Stifler makes amends by engaging in an impromptu dance-off, which inadvertently leads them to Leslie himself, standing quietly beside Bear. With his pride wounded but his determination unbroken, Jim finally secures Leslie's agreement to create Michelle's dream dress, ensuring that the wedding will be a day to remember.

As Cadence (January Jones), Michelle's sister, descends upon the household to lend a helping hand with preparations, Finch finds himself inexplicably drawn to her charms. Unbeknownst to him, Stifler has also set his sights on the lovely newcomer, and in a surprising display of chivalry, he temporarily sheds his rough exterior for a more refined and cultured persona. This makeover proves to be a resounding success, captivating both Cadence and her mother with Stifler's newfound sophistication.

However, Finch's growing jealousy gets the better of him, and he begins to revert back to his old self, embracing an immature, crass, and lecherous attitude that momentarily earns him Cadence's attention. This fleeting victory is short-lived, as it soon becomes apparent that Stifler's earlier guise has not gone unnoticed.

The dress episode, meanwhile, has worked its magic on Michelle's parents, convincing them to give Jim a second chance. They invite the young man to a private dinner, which he lies about to Stifler, claiming everyone will be out of town that night. But Stifler, misinformed, sees an opportunity for a bachelor party and seizes it, arriving at Jim's house with Kevin, Finch, Bear, Fraulein Brandi, and Officer Krystal.

The party gets underway without Jim, who arrives with Michelle's parent to find the house in disarray. Stifler and Finch are forced to scramble to conceal their cohorts, but not before they almost get caught red-handed when Kevin is discovered nearly naked and bound to a chair in the closet. In a desperate attempt to cover their tracks, Stifler concocts an excuse for the chaos, but Jim, ever the gentleman, insists on taking the blame, convincing Michelle's parents that he is willing to go to great lengths to win their daughter's heart and earning their blessing in the process.

As Stifler assumes the role of best man for Michelle's upcoming nuptials, he's entrusted with safeguarding the bride's treasured wedding ring until the big day. Unbeknownst to him, this responsibility will soon turn into a precarious adventure. Upon arriving at the hotel where the ceremony is set to take place, Stifler inadvertently loses the ring when it becomes a canine snack. The rest of his day is spent in a futile quest to retrieve the ring from its new furry friends, who are more interested in playing fetch than returning the precious gemstone. Finally, after hours of waiting for nature to take its course, Stifler manages to reclaim the ring, but his relief is short-lived as he's intercepted by Michelle's parents, who are oblivious to the drama that has unfolded.

In a bizarre sequence of events, Michelle's mother, a self-proclaimed chocolate aficionado, mistakes the ring for a truffle and makes a beeline for it. With no choice but to maintain his dignity, Stifler is forced to follow suit, much to the amusement of Finch, who alone knows the truth behind the ordeal.

Meanwhile, Cadence begins to suspect that Stifler may not be the upstanding gentleman he claims to be, yet she still finds herself drawn to him. She proposes a sultry encounter, but things take an unexpected turn when Stifler stops by the hotel gift shop to procure a bottle of bubbly en route to their tryst. However, his haste leads to a catastrophic mistake: accidentally shutting off the refrigerator that holds the wedding flowers. This unfortunate incident sparks a heated argument with Finch, just as Cadence walks into the scene, her eyes widening in dismay at the sight before her. The encounter is promptly called off.

As tensions simmer beneath the surface, Michelle's world is rocked by an unexpected crisis when Jim's grandmother expresses her disapproval of the union, citing Michelle's non-Jewish heritage as a significant reason for her disdain. This unexpected affront sends shockwaves through Michelle, who takes it personally and struggles to reconcile with Jim's grandmother's outdated views.

As the consequences of his careless actions unfold, Stifler (Seann William Scott) departs the hotel in a state of despair, weighed down by the collective ire of those around him. His melancholic stroll takes him to the flower shop that had provided the arrangements for the wedding, now a poignant reminder of his failures. In the dead of night, he tracks down the owner and presents an impassioned plea, drawing upon the wisdom of his erstwhile coach (a familiar refrain from their previous adventures) to persuade her to undertake a second, Herculean effort in revamping the floral displays.

Undeterred by the enormity of the task, Stifler enlists the aid of his football team, now transformed into an army of florists-in-training. The cacophony of chaos that ensues as they descend upon the wedding hall is a testament to their unbridled enthusiasm and Stifler's unwavering dedication. Jim (Jason Biggs) and Michelle (Amanda Seyfried), still reeling from the previous night's events, are awestruck by this sudden turn of events, while Cadence (Lizzy Caplan) is won over by Stifler's unorthodox charm.

As Finch (Elijah Wood) begrudgingly concedes that Stifler may have been the better match for Cadence all along, the latter's ire is piqued and she vows to forgive her erstwhile suitor. However, Stifler's animosity towards Finch remains unabated, his feelings of disdain tempered only by Finch's subsequent revelation about his encounters with Stifler's mother (Jennifer Coolidge). Stifler's response – a curt "Thank you" – serves as a telltale sign that the old hatred has been rekindled.

In the midst of the wedding proceedings, Stifler and Cadence concoct a plan to steal away for a illicit encounter in a secluded linens closet. However, their assignation is foiled when Cadence is intercepted by her mother, leaving Jim's grandmother (Shirley Knight) as an unwitting substitute. As Stifler enters the darkened closet, believing he has found himself with Cadence, Finch and Kevin (Thomas Ian Nicholas) stumble upon them, revealing that Stifler has inadvertently spent his time with Jim's grandmother, who insists that he complete their assignation before departing.

As the sun sets on the joyous union of Michelle and Jim, the festivities reach a fever pitch, with even Jim's grandmother beaming with delight thanks to Stifler's unorthodox charms. The newlywed's reception is transformed into a whirlwind of revelry, as Jim takes center stage, his dance moves honed to perfection under Stifler's tutelage. With infectious enthusiasm, he invites the entire gathering to join in on the fun, and soon the dance floor is awash with laughter and spinning bodies - all except for Finch, who sits solo, lost in thought.

But just as it seems the evening will belong solely to Jim and his new bride, Stifler's mother (Jennifer Coolidge) makes a dramatic entrance, her presence both captivating and disarming. As she reconnects with Finch, their mutual disdain momentarily forgotten, they exchange banalities, feigning indifference despite the palpable tension between them.

The air is heavy with anticipation as they make their way to Stifler's mother's quarters, where the tantalizing prospect of rekindled passion hangs precariously in the balance. Meanwhile, outside the window, a pair of onlookers - the Milf Guys (John Cho and Justin Isfield) - observe the unfolding drama with slack-jawed amazement, their own desires momentarily eclipsed by the steamy spectacle unfolding before them.

As the camera pans out, the scene dissolves into a surreal tableau, leaving the viewer with a lingering sense of unease and wonder at the unpredictable twists that have brought this group of misfits to the brink of yet another unorthodox adventure.
