As the somber strains of Alex Marshall's funeral commence, a group of his closest friends and University of Michigan alumni gathers at the picturesque Tidalholm plantation in Beaufort, South Carolina. This mourning occasion is hosted by the gracious Sarah and Harold Cooper, who open their home to those feeling the weight of loss.
Among the attendees are a colorful assembly of characters: Sam Weber, a familiar face from television; Meg Jones, a once public defender turned real-estate attorney; Michael Gold, an insightful journalist for People magazine; Nick Carlton, a war-weary Vietnam veteran who has transitioned into an impotent talk-radio psychologist grappling with addiction; and Karen Bowen, an unfulfilled romantic tied to the conservative advertising executive Richard. Chloe, Alex's gentle girlfriend of four months, also mourns his loss.
The following day, Harold sets off for a solitary jog around the plantation grounds. During this personal moment, he confides in Nick about a significant financial opportunity that promises to reshape his life. This tidbit, which was confidentially shared with Alex, piques Nick's interest in exploring a fresh career path. Their conversation subtly unveils Sarah's enigmatic history with Alex—a past steeped in unspoken revelations that have agglomerated among the group.
As Richard departs to return home, Karen decides to remain with her grieving friends. Harold, Nick, Michael, and Chloe take a nostalgic drive to revisit the dilapidated home that Alex and Chloe had aspired to restore together. Meanwhile, Meg shares her frustrations about failed romances with Sarah, expressing her yearning to build a family. Sensing her fertility peak, she pursues Sam as a prospective father, only to be turned down as he underscores his existing struggles with his own estranged child.
As night descends, Michael makes an advance towards Chloe, attempting to persuade her to join him in a lucrative New York nightclub venture. During a heartfelt dinner, Sarah becomes emotional, grappling with the notion that their beloved ideals from the 1960s might have merely been ephemeral distractions. That evening, Meg approaches Sam once again, but her hopes are dashed as he reiterates his decision to refrain from involvement.
The following morning, Harold surprises everyone with quirky running shoes, a gesture illustrating his peculiar entrepreneurial spirit. Nick, however, retreats to the old house, lost in contemplation as he neglects a crucial Michigan football game. In an unexpected turn, Michael offers to step into the role of father for Meg's child, recalling a past encounter they had in college.
Against this poignant backdrop, the lives of these friends begin to unravel, laying bare the intricate tapestry of relationships, hidden truths, and unreciprocated longings that characterized Alex’s journey. As they navigate through layers of complex emotions, each person is compelled to confront the stark realities of existence, the fragility of human bonds, and the transient nature of cherished ideals.
As the halftime whistle blows during a lighthearted game of touch football, the local sheriff finds Nick after he runs a red light, becoming increasingly agitated. Recognizing Sam, the officer offers to dismiss the charges if Nick can fit inside his sleek Porsche 911, mimicking the daring stunts of J.T. Lancer, Sam's television persona. However, Sam’s attempts to emulate the character lead to an awkward mishap. The situation escalates when Nick's accusatory remarks about Harold cause friction, suggesting that their friendly lawman could be biased. Harold rebukes Nick, reminding him that this is his residence and that Nick's reckless behavior could tarnish his reputation.
In a surprising twist, Karen reveals to Sam her deep feelings for him and her desire to leave Richard behind. Unfortunately, her confession ricochets as Sam shares his own marital tribulations, warning her not to repeat past mistakes. Angered and feeling belittled, Karen storms off.
Struggling with the impact of Alex’s sudden departure, the group is plagued by regrets about their long-lost friendship. It becomes seemingly apparent to everyone—except Sam—that Alex had intentionally distanced himself from his friends. Nick, shaken by the trials of life, adopts a cynical view of love and friendship. Outside, Karen seeks to console Sam, resulting in a moment of vulnerability that pulls them closer.
In an emotional encounter, Sarah takes Harold aside and, finding comfort in his embrace, expresses a particular concern: "It's about Meg..." The night unfolds with tender moments shared among the group, especially as Chloe invites Nick to stay in her room, which he once shared with Alex.
With the dawn of a new day, Harold informs everyone that Nick and Chloe will take on the renovation of their old home. Karen begins her preparations to head back to Richard, while Michael decides to set aside his nightclub aspirations. As friends ready themselves to part ways, Michael humorously announces that they have taken a secret vote: they are never leaving the Coopers' abode.
In a surprising conclusion, Nick reveals an old column penned by Michael that narrates Alex’s choice to decline a coveted fellowship. As preparations for departure commence, Michael jovially adds that they've conducted yet another vote: this time, it’s unanimous—they will remain eternally intertwined.
