As Axel drifts into a daydream, he is unexpectedly whisked away to a frigid Arctic expanse, where a solitary Eskimo proudly showcases his grand capture: a magnificent halibut. This vivid scene hints at events soon to unfold against the contrasting backdrop of Arizona, where Axel's cousin Paul is organizing a family gathering featuring Uncle Leo's grand wedding to a much younger bride. These celebratory events serve as a siren call for Axel, who begrudgingly leaves behind his fish-tagging responsibilities in New York City to dive into the family trade of selling Cadillacs.
Upon his arrival, Axel encounters two enigmatic women who will significantly alter his life’s path. Elaine, a visionary fueled by an unwavering passion for flight, and her stepdaughter Grace, who finds herself cloaked in a cloud of melancholy, yearning for self-sacrifice and even dreaming of reincarnating as a turtle. As the three navigate the dynamics of family dinners, Axel and Paul grapple with the ever-levitating chair that Grace occupies, symbolizing the transcendent challenges they are about to face.
Axel's feelings for Elaine deepen, leading him into her ambitious quest to create a flying machine. However, their collaborative dream frequently faces setbacks due to the disruptive influence of Grace. When Leo and Paul intervene, urging Axel to refocus on the family business, Elaine fiercely holds onto her dreams, even brandishing a shotgun in a desperate attempt to protect her vision. Yet, undeterred, Axel and Elaine persist, culminating in their flying machine crashing spectacularly into a tree.
As tensions escalate, Axel's determination is tested amidst various crises. He ponders the idea of ending the struggles faced by Elaine and Grace, but finds the courage to spare them. Instead, he extends an invitation for them to join Paul during his talent show—a tribute to Cary Grant’s iconic crop-duster scene from North by Northwest. As the night unfolds, the judges return a lackluster score of 1, but Axel's awakening moment arrives when he learns of Leo's health crisis. In a frantic attempt to save his uncle, Axel calls for emergency services, abruptly halting the evening’s festivities.
The day before Elaine's birthday, Axel and Paul arrive at her home, imbued with a sincere apology. Initially, Elaine is irritated with Axel for his long silence, but her anger subsides, allowing for a heartfelt reconciliation. The following day, while blowing out the candles of her birthday cake, her friends surprise her with an extraordinary gift: a sleek airplane that symbolizes the freedom and adventures that await.
However, their collective joy is soon disrupted by an unexpected storm. As the others seek refuge indoors, Grace bravely ventures outside on her mission to release her cherished turtles, encouraging them to "Go play." Meanwhile, Axel and Grace retreat upstairs for a gift-wrapping ritual, imbuing each present with distinct significance.
As the evening progresses, discussions shift to the theme of mortality, with each friend expressing their wishes regarding how they envision their final moments. With quiet determination, Grace ascends to the upper level, adorning herself in a flowing white shift and a veiled hat before slipping into the night, prompting Axel and Elaine to rush after her in a frantic effort to intervene.
In the wake of Grace's tragic departure, the group is left to contend with the aftermath of her actions. The once-hopeful airplane now lies in ruins, struck down by a lightning bolt—a poignant reminder of fate's unpredictability. Days later, Axel is compelled to visit Uncle Leo's forlorn Cadillac showroom, where he collapses onto a glossy new model, surrounded by the soft purrs of a newly arrived kitten.
As the film concludes, Axel's subconscious leads him to a whimsical realm where he and Uncle Leo don Eskimo attire amidst a lively frozen tundra. With exhilaration, they engage in the thrill of catching a majestic halibut, their Inuktitut chatter warming the crisp Arctic air as the sun begins to rise on this fantastical scene.
