Trudi Angermeir, who has long held a dream of visiting Japan with her husband, Rudi, is devastated to discover that he is terminally ill. Rather than revealing the heartbreaking news to him, she suggests they take a trip to see their youngest son, Karl, in Tokyo—a plan Rudi ultimately declines. In a slight compromise, he agrees to visit their daughter and other son in Berlin.
Once they arrive in Berlin after their journey from their quaint Bavarian village, their oldest son, Klaus, picks them up and takes them home, where they are greeted by his wife, Emma, and their children, Celine and Robert. The mood is less than warm, and the visit feels burdensome to Klaus and the others, who reminisce about feeling neglected while growing up in comparison to their younger brother.
The next day, Karolin's girlfriend, Franzi, who seems to have a fondness for the elderly couple, takes them out to see the sights. Later that day, their daughter joins them at her and Franzi's place, but the visit quickly turns tense, prompting Trudi and Rudi to return to Klaus’s home. A minor hiccup occurs when they struggle to purchase their S-Bahn tickets, leading to a snap from Rudi. In an effort to lighten the mood, Trudi suggests they visit a nearby beach.
As the days unfold, the elderly couple venture to a beach resort, spending tranquil days strolling along the coastline. However, tragedy strikes when Rudi discovers Trudi has passed away in her sleep. In the aftermath, their children—alongside Karl who flies in from Tokyo—rally around Rudi, who is lost in his grief. He resents returning to a home filled with silence, and the only attendees at Trudi's burial are Franzi and himself.
Time passes and Rudi finds himself compelled to fly to Tokyo, staying in Karl's modest flat. Unfortunately, Karl’s hectic schedule leaves little room for shared experiences, leaving Rudi alone with memories of Trudi. In a touching tribute to her memory, he begins wearing her clothes, determined to keep her spirit alive. As Rudi navigates through the bustling Tokyo streets, he gradually discovers the city’s quieter corners, feeling a connection to Trudi in the process. One day, while leisurely wandering, he encounters a young dancer named Yu in a park.
As they form a bond, Rudi learns that Yu is an orphan, using dance, particularly Butoh, to cope with her grief. Their friendship deepens, although it causes tension with Karl, who disapproves of Rudi's choices. After learning that Yu is homeless, Rudi invites her to stay with them, eliciting a dispute with Karl. The following morning, Rudi leaves quietly and proposes a trip to Mount Fuji, determined to fulfill Trudi's dream. They embark on this journey, but upon arrival, the mountain remains elusive behind clouds.
They register at a ryokan and spend days hoping for a clearing. Rudi’s health begins to falter, and one night, as he succumbs to fever, Yu tends to him. One clear dawn, Rudi awakens to find Mount Fuji visible—a moment of joy that compels him to don Trudi's kimono and rush to the lakeshore for a Butoh dance inspired by her spirit. The poignant moment is followed by Rudi collapsing and passing away.
In the wake of his death, Yu discovers an envelope filled with Rudi's savings, a heartfelt gift left for her. Karl arrives, and together they perform a traditional ceremony to honor Rudi's ashes. After returning to Tokyo, they say their goodbyes outside Karl's building.
Back at their parents' home, Klaus, Karolin, and Karl ponder the loss of both Trudi and Rudi. Franzi reflects on Rudi’s later happiness, stating that “he probably was happy in the end.” The film concludes with Yu back in the park, dancing under the cherry blossoms, wearing Rudi's hat amidst her grief, a beautiful homage to the love and memories they shared.
