Grace arrives at her childhood home to take her mother, Heather, on what Heather believes is a seaside vacation. The house is alive with music, half-finished paintings, colorful laundry blowing in the wind, and Heather herself: glamorous, chaotic, and halfway through her beauty routine. Though Grace has arrived with a heavier purpose, Heather immediately sits her daughter down and begins brushing her hair, returning them both to a familiar ritual from Grace's childhood.
As they prepare to leave, the severity of Heather's condition becomes impossible to ignore. They discover her beloved cat, Humphrey Bogart, dead beside an empty water bowl. Heather responds with characteristic optimism, while Grace is forced to confront how badly things have deteriorated and how long she has allowed herself to look away.
The two begin driving down the California coast. Heather drifts between lucidity and memory, reminiscing about her late husband, their wild younger years, and family road trips with Grace. At a gas station, she briefly forgets that her husband is dead and insists they wait for him to return. Later, the sight of the ocean pulls her back into a childhood game she once played with Grace. Despite herself, Grace begins to enjoy being her mother's daughter again.
When they arrive at the Flower Foundation Memory Care Home, Heather realizes that Grace has deceived her. Panicked and furious, she runs toward the beach, strips off her clothes, and walks into the surf. For a fleeting moment, she imagines herself beside her late husband as she remembers him decades earlier.
When the memory disappears, Grace finds her mother alone at the water's edge. Heather briefly fails to recognize her before returning to the present. She refuses to say she is ready, but begins walking toward the home anyway.
Inside her new room, Heather attempts to regain control in the only ways she knows how, inspecting the room, complaining about the mattress, and making plans for her clothes and paintings. When she tries to brush her wet hair, her trembling hands make the task difficult.
Grace quietly takes the brush from her.
For the first time, the daughter begins caring for her mother in the way her mother once cared for her, gently combing through Heather's hair, strand by strand.
