Alma Duval Shirley Booth is a Louisiana housewife who plans a quiet 45th birthday celebration for her husband Jack Duval Anthony Quinn. As the date nears, it becomes clear that the celebration is overshadowed by a painful truth: Jack is carrying on with a much younger woman named Ruby Valerie Allen behind Alma’s back. Alma’s adult children try to break through her stubborn, hopeful denial, but she clings to a dream that everything can somehow be put right if only they return to their old life.
The birthday dinner is a tense stage for a family that feels increasingly fractured. Jack picks a heated fight with his eldest son, Buddy Duval Earl Holliman, ridiculing his business ideas and daring him to show backbone. The clash intensifies the undercurrents in the room, and no one dares to touch Alma’s homemade cake. After the meal, Jack takes his teenage son Billy Duval Clint Kimbrough aside for a lesson in manliness—drinking, swagger, and bravado—leaving Billy shaken and tearful as Jack confesses his own discontent with the life he leads.
Back home, Alma shares a portion of the birthday cake with her neighbor Fan Eileen Heckart, who tries to nudge Alma toward a more carefree, bold attitude—suggesting smoking and casual drinking as a way to impress Jack. Meanwhile, Virginia Duval Shirley MacLaine, Alma’s daughter, watches another chapter unfold in this family saga when her own relationship with Wyatt Warren Stevens is tested; Wyatt, a medical student, bluntly tells Virginia that marriage isn’t possible right now because he needs someone of greater social standing and wealth. The web of unspoken expectations grows heavier, and Alma clings to a convenient memory: if they could just move back to New Paris, where the couple started out, perhaps happiness could be recaptured.
But reality intrudes with a painful strike of truth. Alma, seeing the rift widening, slaps Jack after discovering his affair. He resolves to leave, seeking a fresh start in Florida. On the road, Ruby pushes him to speed, and just before a car rams into construction detour signs, Jack yells Alma’s pet name, "Mumma."

The crash claims both Jack and Ruby, leaving Alma and the children to mourn a sudden end to their fragile illusion. They return to New Paris for the burial, confronting a landscape and a family that have changed beyond recognition. The town’s familiar corners now feel hollow, and Alma begins to grasp that the past she clung to is unrecoverable. Back at home, she resists the idea of a holiday to escape her grief, insisting there’s nobody to watch the children. Yet as the moment lingers and the children look on, she begins to sense that even the old comforts—home, routine, and predictable happiness—have shifted into something irrevocably different. The film closes on a quiet, unsettled acknowledgement: the past is no longer a safe harbor, and the family must reckon with this new, more complicated truth.
This story is built around a tense, emotionally charged web of loyalty, denial, and the stubborn pull of memory. The characters carry each other through a landscape that blends Southern warmth with a blunt, unsentimental realism, where the dream of returning to a simpler life collides with the undeniable changes of time, love, and consequence.
