Eleanor and Adam Weller find themselves in a NYC café, where they are set to finalize their divorce. The atmosphere is tense as Adam's overly friendly demeanor starts to irritate Eleanor. Their conversation takes a heated turn when Adam states he cannot attend their daughter Maud's graduation because of the opening night performance of his old play in London. This statement triggers a flood of anger within Eleanor, as it reminds her of the times Adam's European shows were often a facade for his infidelities. As the tension rises, they nearly create a public scene due to their emotions.
Meanwhile, in the comfort of Adam's apartment, Maud is focused on completing her PhD while also trying to flirt with Sam, who is busy renovating the kitchen. However, Sam, feeling uncomfortable with her advances, tries to push her away. As the narrative unfolds, Adam's friend Ruth Frank reaches out to him, prompting Eleanor to press for Adam to return her call. Although Ruth is the widow of his late best friend Vincent, Adam seems detached, showing little empathy after five years since Vincent's passing.
Maud then encounters her thesis advisor, Brian, who attempts to rekindle an old flame, but she firmly shuts him down, citing her ongoing thesis on morality as a reason to avoid hypocrisy. At the same time, Eleanor discusses her own marital issues with a fellow psychiatrist. She expresses her frustration over a patient’s passive approach to her marriage, revealing her own struggles as she recognizes that she is projecting her feelings onto the situation.
As the plot progresses, Adam meets with his new partner, Sandrine, and faces his critic, Richard Gordon, who is working on a revealing biography about Vincent. Realizing the encounter is turning uncomfortable, they decide to cut their meeting short. Subsequently, Adam visits Ruth, who presents him with an unpublished play by Vincent and seeks his opinion, eager for his validation.
On a different note, Maud spends time with Sam, who, having lost his daughter Zahra, struggles to open up fully due to his emotional scars. Concurrently, Eleanor is on a date with Adam's brother Paul, who reveals that he has just gone through a divorce himself. Insisting that Adam has been foolish to let Eleanor go ignites frustration in Eleanor, leading to an unexpected kiss from Paul, only to be met with a slap as she rushes away.
As the weekend unfolds, Adam’s producer, Ken Yates, reaches out to discuss both Sandrine’s dental issues and the upcoming play opening. Adam is also keen on revisiting the project for a Broadway revival. Shortly after apologizing to Paul for the earlier slap, Eleanor finds herself in a passionate situation with him, while Maud's relationship with Sam grows deeper, even as both navigate their complicated pasts.
As events spiral further, Maud learns of her pregnancy, which presents its own set of challenges as she grapples with morning sickness and emotional turmoil. After the birth of her child, she decides to check herself into a mental health facility, seeking distance from the chaos surrounding her. Meanwhile, Eleanor and Adam share an intimate moment amidst their chaotic lives, leading to a unique dynamic of co-parenting.
Ultimately, as the successful opening night of Adam's play approaches, the threads of their lives begin to intertwine in unforeseen ways, leading to moments of truth and heartfelt connections. By the time the play garners critical acclaim, Eleanor finds closure in moving to Cincinnati with Paul, while Maud embraces her new life with Sam and their child. In the end, the journey explores the complexities of relationships, art, and the pursuit of happiness, leaving the characters in a space of growth and newfound beginnings.
