After the death of her mother in Japan, Hanaka discovers a bundle of letters that reveal a secret, decades-long relationship with a Berlin painter.
Hanaka, a German-Japanese archivist living in France, receives news that her estranged mother, Johanna, has passed away in Kobe, Japan. Hanaka travels across the world to close down her mother’s high-end fashion studio. Tucked away inside the silk lining of an unfinished linen jacket, she uncovers a bundle of airmail correspondence spanning over twenty years. The letters were sent from a single source: an eccentric painter named Kusmín based in West Berlin during the Cold War. Realizing her mother lived a secret parallel life of profound romantic passion, Hanaka travels to Berlin to track down the painter, assembling a beautiful new picture of her family's past.
