As the curtains rise on the second chapter of "The Four Seasons," Anne (portrayed by Kerri Kenney) enthrals the gathering with tales of the opulent arch she secured for their silver jubilee anniversary. She reveals how Nick (played by Steve Carell) surprised her with a kiln, which she ignited for its inaugural firing, crafting an identical replica of their wedding platter—a cherished item shattered years ago.
In a private moment, Jack (Will Forte) urges Kate (Tina Fey) and Danny (Colman Domingo) to inform Anne of an impending revelation. Skeptical, Danny dismisses vow renewals as mere formalities, suggesting they merely observe the ceremony as spectators. Their resolve crumbles when they discover Anne has invited her entire acquaintance. Claude (Marco Calvani), bubbling with excitement about the impending festivities, joins them outdoors.
Kate, seeking to reassure Jack, encourages him to focus on the present rather than indulging in overwrought emotions. She suggests a brief respite for him while she attends to matters downstairs. Jack ponders whether they should alert Nick, ultimately leaving a message for him. Claude, still grappling with accessing the customer portal despite assistance, tries to persuade Danny to prioritize his surgery. Danny, however, insists on attending the installation, only half-heartedly heeding Claude's advice to prepare for the celebration.
Anne approaches Claude, inviting him to serenade the couple during the ceremony with their wedding song, to which he graciously agrees. Meanwhile, Jack's attempts to maintain composure falter as he assists Anne with her hair, revealing his inner turmoil. Kate confides in Danny about Jack's distress, uncovering Danny's deceit about needing to be away. Danny admits he merely seeks time to contemplate his surgery, but Jack's interruption labels them all as insensitive, fearing Anne's public embarrassment.
Each of them has now contacted Nick, sparking Kate's fear that he might have fled in panic. Jack resolves to confront Anne, yet finds himself unable to do so, instead assigning himself the task of reading "When Two People Are At One" during the ceremony. In a twist, Jack inadvertently mentions that Kate has something crucial to share, complicating matters further.
Danny checks on Claude, who is preparing to sing, confessing his unnecessary pretense about a Miami trip and uncertainty about surgery. Claude, disheartened by Danny's revelation, finds himself caught in a web of unspoken truths. As the ceremony's commencement nears, anticipation thickens, with Don (Alan Alda) sharing anecdotes about his daughter's multiple weddings, briefly engaging Danny and Kate before they step outside.
Kate and Danny's conversation about concealing truths from Claude intensifies, prompting Danny to confront Claude in Kate's presence. Claude brushes off Nick's intentions lightly, surprising Danny with his nonchalance. Jack, signaling Kate, admits his failure to tell Anne, now tasked with a poignant reading that resonates deeply. Amidst the turmoil, Danny admits his falsehood to Claude, who is left dissatisfied and concerned for his friend's well-being.
He asserts that Danny consistently employs such tactics to attain his desires, leaving Claude perplexed as to why Danny would resist this particular course of action. Eventually, Danny succumbs and concurs to undergo the procedure the following week. As they depart, the kiln emits a telltale smoke, signaling trouble. Kate engages in conversation with Lila (Julia Lester), who reassures her that the ceremony will lose its awkwardness once it commences. Kate checks in on Anne, intending to inform her about Nick. However, her revelation is preempted by Nick's message, announcing his imminent arrival within five minutes. Kate dashes outdoors to inform everyone of Nick's approach, emphasizing to Jack that Anne would not be caught off guard today. Motivated by a desire to mend the situation, Kate sees her action as a corrective measure. They reminisce about how Jack might have navigated the scenario. Nick finally arrives and joins Anne's side. Claude rises to serenade them, only to be interrupted mid-song by Anne, who corrects him that it's not their wedding tune. Claude's realization dawns that Danny had deceived him, but Anne encourages him to press on. Danny offers an apology, vowing to improve his communication skills following his surgery next week. Claude affirms their commitment to getting those tattoos.
Anne reads her vows to Nick, highlighting how he personally installed her kiln despite it being a job for a professional. It's then Nick's turn to reciprocate. But before he can utter a word, the kiln erupts in an explosive blaze, casting an unexpected drama into their special moment.
