A.C.O.D.

Carter Spencer, Adam Scott is the central figure in a tense, wry family drama that unfolds after a pivotal ninth-birthday party at the Spencer lake house. From that moment, his parents, Hugh and Melissa, played by Richard Jenkins and Catherine O’Hara, shape his world with a steady stream of emotional manipulation, quiet character assassinations, and damaged new relationships. The brothers-turned-young-men, especially Carter and his sibling Trey, endure a pattern of strained bonds as their father remains distant and often unfaithful, while their mother relentlessly counters his provocations—leaving both boys to forge their own fragile paths toward adulthood.

Trey, Carter’s brother, moves the plot forward when he spontaneously proposes to Keiko, his girlfriend of four months, and asks Carter to broker a ceasefire between their feuding parents for the sake of the wedding. The request drags Carter into a deeper exploration of family history. He seeks counsel from Dr. Lorraine Smith, a therapist he once believed was merely a teen confidante, and discovers something startling: he was one of her subjects in a best-selling book about the children of divorce. This revelation prompts him to seek out the book and read it in full, fuelling a growing resolve to force the adults to behave in a civil, wedding-ready manner.

Amy Poehler steps into the story as Dr. Lorraine Smith, whose presence becomes a catalyst for Carter’s plan. At first, Carter struggles to coax Hugh and Melissa into meeting as a single, shared lunch, but he succeeds by orchestrating a scenario that leaves them with no escape until they agree to cooperate for the sake of civility at the wedding. The staged “meal together” becomes a turning point, and for a moment the Spencer brothers feel cautiously hopeful about a truce.

As things move forward, a new wrinkle arrives in the form of Hugh’s third wife, Sondra, played by Jane Lynch. She introduces a painting at the restaurant, and her appearance coincides with the publication potential of Dr. Smith’s next book, which Carter inadvertently inspires. The web of secrets tightens when Sondra calls Carter for details about a supposed golf outing with his father, and Carter’s curiosity leads him to investigate behind the scenes. He learns more than he expected: his parents’ marriage is underpinned by an ongoing affair.

The discovery ripples through every relationship. Carter confides in his longtime girlfriend, Lauren, portrayed by Mary Elizabeth Winstead, but his revelations ripple outward, affecting the wedding plans and the family economy alike. Meanwhile, the adults continue to press for control and status: Melissa’s husband, Gary, provides a generous check to the stepsons in a bid to sway the wedding, while Hugh tries to minimize the damage by insisting the affair was a one-time lapse. Dr. Smith, sensing that Carter remains stuck in a defensive cycle, begins to interpret his behavior as a reaction to childhood trauma—an attempt to maintain control over his own life.

Carter’s investigation widens when he meets Michelle, another subject of Dr. Smith’s work, and he discovers that the tangled history of the Spencers is far more intricate than anyone admits. At a tux fitting, Hugh’s absence becomes another sign of the growing rift, and Carter confronts Melissa directly, only to learn more about the depth of the betrayal. The parents’ separate returns to Carter’s life—at a tea house gathering with Keiko’s parents and during a late-night confrontation—reveal the true extent of the couple’s indiscretions.

Armed with evidence, Carter brings two file boxes of receipts and testimony from Melissa’s side of the affair to Dr. Smith, insisting she confront Hugh and Melissa. That evening, a late-night encounter between Carter, Melissa, and Keiko’s arrival complicates the situation, culminating in a kiss between Carter and Melissa that signals a turning point for the entire family. At the cake tasting, Carter finally reveals the truth of their parents’ affair to Trey, and the weight of the revelation rocks the wedding plans. Sondra files for divorce from Hugh and indirectly triggers the loss of the restaurant space, sending ripples through the family business.

The mounting tension culminates in a dramatic confrontation in the Spencer garage, where Carter’s family pressure collapses into a defensive stand. Carter quits the family, and Keiko’s wedding is paused as he withdraws. The fallout continues at Lauren’s parents’ anniversary party, where Carter’s proposal to Lauren backfires—she decides to end their relationship, at least for the moment.

In a final act of catharsis, Carter transports the divorce evidence back to the lake house—the place that started this entire saga 20 years earlier. The plan is to destroy the painful past once and for all. When Gary arrives and others begin to assemble, the house is unintentionally consumed by flames—an accidental blaze sparked by Sondra’s misstep with a match. Yet the arc does not end with ruin: Carter volunteers to buy back the lake house, and time passes as the community stages a new reading of A.C.O.D., the organization at the heart of the book Carter discovered, now featuring the adult subjects as a reminder of how far they’ve come.

A year later, the Spencer men—three brothers in matching suits—are brought together at a church for a wedding, signaling a fragile but enduring bond that survived decades of hurt. The ending leaves Carter, Trey, and their father and mother facing a new future—one built on complex, painful but necessary honesty, strengthened not by perfection but by the hard work of healing and reconciliation.
