The film concerns a trip taken by two women, Jinko (Aoi Miyazaki) and Motoko (Sakura Ando), and their driver, Haraki (Shiori Kutsuna), to see Miki (Kazue Fukiishi), an old friend now living in a psychiatric hospital after attempting suicide. Jinko and Motoko have not seen Miki in six years, and the trip becomes a meditation on their own lives and sorrows, as well as reconciliation for their guilt of not being able to help her before.
