Taeko is 27 years of age, unmarried, and it's 1982, and it has lived her existence in Tokyo. She decides to see her family from the countryside, and as the train travels throughout night, memories flood back with her years: the initial Cuban stirrings of love, the beginning of puberty, and the frustrations of math and boys. At the channel she is met by man Toshio, as well as the experiences with him begin to beg her to longings. In lyrical switches between the current and the history, Taeko contemplates her life's arc, and wonders if she's has been faithful to the fantasies of her childhood self.
