As Audrey (Alicia Silverstone) arrives at her brother Liam’s (Jake Hoffman) wedding celebration in the Hamptons with her husband Ethan (Tom Everett Scott), a chaotic series of events begin to unfold, resembling an imperfect storm. Just before they reach the festivities, Ethan spills coffee all over Audrey, leaving her ill-prepared for the casual chic vibe that greets her during the opening Shabbat dinner among the French family. This awkward situation grows even more uncomfortable when Liam reveals he has opted to collaborate with an architect other than Isaac (Charlie Bewley), Audrey’s ex-boyfriend, igniting a profound sense of betrayal and resentment within her.
The following day, tension escalates as Audrey finds herself in a candid discussion with Clemence (Mathilde Ollivier) that leaves her emotionally unsettled. While gearing up for an exhilarating water-skiing adventure, Clemence’s intrusive inquiries about Audrey’s peculiar midriff bulge catapult her into a whirlwind of feelings. In a reckless moment, Audrey pushes the speedboat to its limits, prompting her to confront the repercussions of her impulsive actions.
As the wedding celebrations unfold, Liam and Clemence encounter several hurdles that risk derailing the entire event. From a painful basketball injury to a dramatic exit by the bride-to-be, and a few unwanted guests, Audrey finds herself at odds with both her brother and his fiancée. The situation reaches a climax when she overhears a startling revelation about Clemence’s past, leaving Liam on the verge of calling off the wedding entirely.
In the midst of this emotional tempest, Audrey feels increasingly like an outsider, her place within the wedding party slipping away, and her relationships growing strained. As she grapples with hurt feelings, unresolved conflicts, and unreciprocated love, Audrey realizes the necessity of stepping aside to let true love flourish—even if it means sacrificing her own aspirations.
During the reception, Isaac makes a daring move, inciting Ethan’s jealousy and causing him to storm off, while Audrey contemplates her feelings amid the unfolding chaos. In a moment of misguided desperation, she turns to an old acquaintance—the power of ecstasy—in an attempt to reconnect with Clemence and restore joy to the atmosphere. Unfortunately, this impulsive decision leaves her feeling ill and discombobulated.
Rushed to the hospital in an ambulance, Audrey must reckon with the consequences of her actions and the ripple effects they have on others. It’s here that she begins to gain a fresh perspective—a world where love transcends expectations, even if it requires setting aside her own desires. With this newfound clarity, Audrey embarks on a journey to mend fences, understanding that the greatest gift one can offer is the liberty for others to pursue their own paths, even if it means relinquishing her own sense of belonging.
As dawn breaks over the serene landscape, Audrey quietly slips away, leaving behind a trail of thoughtful reflection. Accompanying her departure is a heartfelt apology note for the unaware couple, along with a candid slideshow that captures their carefree, skinny-dipping moments. This photographic testimony stands as a poignant reminder of the fragility of relationships and the transient nature of experiences.
Meanwhile, back where the chaotic reverie began, Ethan awakens to find Audrey has already left, leaving only the soft remnants of his subconscious thoughts. As he stirs from his dreamy slumber, he is met with the gentle recollection of Audrey, who returns to gather her thoughts and resolve their issues. Together, they embark on a path of self-discovery and rejuvenation, their journey illuminated by the subtle light of dawn and the hopeful promise of new beginnings.
