Audrey (Alicia Silverstone) travels to the Hamptons with her husband Ethan for her brother Liam's wedding, a weekend that also marks Audrey turning 40. The trip is crowded with emotions and expectations as Clemence, a young French woman, joins the group, and the weekend begins with a casual yet charged Shabbat dinner that sets the tone for what follows.
Moments before they arrive, a spill changes the plan: Ethan knocks coffee across Audrey, leaving her little chance to change into something appropriate for the opening Shabbat dinner. At the table, Audrey is introduced to Clemence's family, and the tension slowly builds as she learns that Liam intends to proceed with major renovations to the house under a different architect, a move that undermines Audrey’s own work and vision. The sense of unspoken competition and longing lingers, especially as Audrey confronts the reality that her ex, Isaac, has been invited to the wedding despite past tensions.
The next day brings a buoyant but uneasy energy as the group goes water-skiing. While Audrey is towel-drying, Clemence bluntly asks if she’s pregnant, and an incongruous physical detail—an apparent hernia—makes Audrey self-conscious about how she presents herself. The moment intensifies when Audrey, feeling the pressure of appearances, drives the speedboat too fast during Clemence’s turn, revealing the fragility of control in a day meant for celebration.
As the celebration continues, Liam suffers a nose injury while playing basketball, drawing concern and a shifting mood from those around him. The bride-to-be reacts with visible frustration, storming off, and the wedding dynamics become more strained. The plan for a pristine white dress ceremony is put to the test when Audrey’s gown is spoiled; she scrambles to find a replacement in town, caught between the desire to fix the moment and the growing recognition that she’s no longer an insider in Liam’s circle.
A whispered conversation reveals that the bride recently had an abortion, and Audrey relays this to Liam, sparking a near-break in the ceremony as he contemplates canceling the wedding. Despite the upheaval, the wedding proceeds, but Audrey’s role is dramatically diminished; she is no longer part of the wedding party, and the atmosphere is thick with unresolved resentment. To complicate matters, her ex is openly present, stirring old emotions as the party unfolds.
At the reception, Isaac makes a direct pass at Audrey, who is thrust into a moment of temptation and restraint as Ethan storms off, likely driven by his own micro-dosing experience. Audrey resists Isaac’s advances, choosing to resist the impulse to recapture what once was, even as the evening grows more intimate and unpredictable.
In a bold, unsettling move meant to bridge a connection with the bride, Audrey sprinkles ecstasy onto the wedding cake. The two women experience a dangerous, twisted bond as they connect, but the effect is immediately harmful: the bride falls violently ill, and an ambulance arrives. In the quiet reveal, Audrey confesses that she sprinkled the drug on the cake, a moment that exposes the fragility of boundaries and the lengths to which people will go to force a moment of happiness.
The admission becomes a turning point for Audrey. She realizes she can’t stand in the way of true love, even when it’s messy or painful, and she begins to see the consequences of her actions more clearly. By dawn, she leaves the wedding, slipping away with a note of apology for the couple, accompanied by a slide show of the pair skinny-dipping together as husband and wife—a bold, intimate memory the bride and groom may carry forward.
As Audrey heads home in the early morning light, she discovers that Ethan has slept through the microdose, softening the rift between them. The couple reconciles on the drive back, acknowledging the complexity of love, forgiveness, and the personal growth that comes from stepping back rather than stepping in. The weekend in the Hamptons closes on a note of fragile hope, with new understandings about loyalty, boundaries, and the unpredictable ways that people find their path to happiness.
