As the seventh installment of "The Four Seasons" unfolds, Jack (portrayed by Will Forte) engages in a heated conversation with Vivian over the phone, while Kate (Tina Fey) navigates the steering wheel with focused determination. Meanwhile, in a separate vehicle, Claude (Marco Calvani) expresses his eagerness to reunite with everyone to Danny (Colman Domingo), who shares the sentiment but with reservations, hinting at the intention to broach the topic of setting boundaries with Kate. Jack inquiries about the contents of his father's basement, volunteering his assistance in sifting through the clutter and deciding what stays and what goes.
Nick (Steve Carell) and Ginny (Erika Henningsen) converse about halting their journey momentarily to stock up on groceries. Upon arrival, Ginny's face lights up as she spots her friends awaiting them on the porch overhead. Kate discovers that Claude will be taking charge of the culinary duties, shortly followed by Anne's (Kerry Kenney) arrival. Anne introduces Terry (Toby Huss) to the group, recounting their encounter at a pottery convention in Poughkeepsie. Danny regales them with tales of Christmas past, while Jack mentions the basement flooding ordeal and his sister's inclination to purge everything.
Terry strums an acoustic guitar, adding a melodic backdrop to the gathering. Claude drags Danny aside for a confidential chat, revealing his belief that they might have shared a fleeting encounter with Terry in Barcelona, eighteen years prior. Danny embraces this unexpected mystery with enthusiasm. Kate confronts Jack about her frustration and resentment stemming from his lack of assistance with the groceries. Jack contritely vows to be more considerate moving forward. Kate's attention is drawn to Jack's buzzing phone, adorned with messages and a missed call, which he swiftly secures.
Nick learns that Ginny's friends are indulging in immunity shots and is introduced to Rachel (Taylor Ortega), Sarah (Simone Recasner), and Jett (Adam Weppler). His narrative begins to weave its magic until Colby (Tommy Do)'s arrival interrupts, announcing his affection for Paris and potential relocation. Ginny whispers to Nick that Colby is a globe-trotting social media sensation, his TikTok filled with packing videos.
Later, Claude grills Terry in an attempt to verify if he was indeed the Barcelona fling. Kate approaches Danny, hoping to mend fences. Danny emphasizes the importance of establishing clear boundaries. Kate self-blames, confessing her tendency to lash out when unhappy. She apologizes for her remarks about Claude and reveals that Dr. Suzanne has been helping her. When Danny probes about therapy, Kate admits they argue less but also communicate less, noting a three-month dry spell in their intimate life. Worried by this anomaly, she opens up about her concerns. Danny doubts Jack's infidelity, citing Kate's logistical challenges. Claude suggests the need for a Terry strip-down to verify a distinctive birthmark, a detail from their Barcelona encounter. Danny concurs, planning to make it happen.
After a ski session, Ginny's friends playfully dub Nick "The Carl" due to his competitive spirit. Later, Nick captivates everyone with another enchanting tale.
Danny recounts the identical tale to the older crowd, who then reveal that their hot tub had malfunctioned. The repairman mended it but oddly hesitated to depart. Anne speculates that he might have been homeless, while Nick clarifies that he eventually relented but was bound not for his own abode but to his brother's residence – a brother who, Nick adds with a hint of drama, turns out to be none other than Kenny Loggins. Ginny's companions remain perplexed, Terry alone understanding the reference. Claude, undeterred, advocates for a post-dinner dip in the hot tub, an idea Terry warmly endorses. Nick finds himself tasked with enlightening Ginny's friends on the identity of Kenny Loggins.
Later, Danny reconnects with Nick, and their conversation inevitably circles back to the enigmatic repairman. Prior to sharing tales of Ginny and her circle with Kate and the rest, Nick learns more about Terry from Danny. Jack diverts Nick's attention by recounting stories of his father's basement. Meanwhile, Ginny dials in to check on everyone, her voice a warm greeting over the phone lines. Nick assures her he'll join them downstairs shortly and bids farewell to Anne and the rest as the video call draws to a close.
In a private moment, Kate confides in Danny her anxiety each time Jack glances at his phone, prompting Danny to suggest she confront him. Claude persists in his mission, determined that everyone will join him in the hot tub. Kate engages Anne in conversation about Terry, who Anne notes might not cross their paths again post-trip due to his peculiar accessory – a delicate silver anklet. Anne reveals her pride in stepping back into the social scene, only for the atmosphere to be momentarily disrupted by a falling ball. Terry's aggressive advances towards Anne ensue, while Nick finds himself unexpectedly engrossed in Anne's farm game. Ginny discovers him and her expression is far from pleased. Nick excuses himself, saying he lost track of time, but senses a growing detachment from her friends. Ginny counters that being around his friends isn't always a picnic either, and she strides off with her friends, leaving Nick to his thoughts.
Jack and Kate climb into the hot tub together, but his attention is snagged by an incoming message on his phone. As Kate attempts to discuss something crucial, Jack remains glued to his screen. Kate's curiosity turns to suspicion; she demands to know with whom he's been intimate. Danny, overhearing the exchange, realizes Kate has provoked an argument. Jack strives to convince Kate of his innocence, attributing the changed passcode to his recent foray into LegalZoom for mediation purposes.
Jack insists that his actions were solely provoked by Kate's incessant hints of impending departure. Kate, on the other hand, contends that she is tethered to him out of fear that his world would crumble without her meticulous care. She laments, pointing out that she shoulders all responsibilities while Jack contributes nothing. Jack, mindful of not spoiling the vacation for the others, retreats indoors, with Kate hot on his heels. Meanwhile, Claude and the rest of the group make their way to the hot tub. Upon realizing Terry is not the person he's seeking, Claude heads back inside with Danny, leaving Anne and Terry alone in the bubbling waters. Anne proposes a much-needed conversation.
Kate, whose phone took an unplanned dip into the water, frantically attempts to salvage it. Claude comes to her rescue, placing the device into a bag of rice to draw out the moisture. Elsewhere, Nick ventures to the store to gather items that might please Ginny's friends. An abrupt encounter with a hasty passerby prompts Nick to jestingly dub him "the Carl."
From her window, Kate catches a glimpse of fireworks just as her phone miraculously comes back to life, flooding her with messages from Ginny. With a heavy heart, Kate informs Jack that Nick, who was driving solo, was involved in a fatal accident. The news strikes like a bolt of lightning. When they try to break the heart-wrenching news to Anne, they find Terry in the midst of attempting to comfort her. Anne's emotions unravel upon hearing of Nick's demise; she pleads with them not to inform Lila. Terry, in an attempt to soothe her grief, begins singing Elton John's "Candle in the Wind" only to be politely asked to cease.
