An old man has to move to his son's new house. His wife is hospitalized and cannot move together. A few days after moving, he decides to go back to see his wife, though being opposed by his son.

Akito has been the ears and voice of his mother, Reiko, since he was a child. Reiko was born deaf and has long dreamed that her son would become a professional pianist. Akito is studying to enter a prestigious music college, but he begins to have doubts about his talent. One day, he meets Izumi, a deaf girl who plays in a street band. He is attracted to her positive nature, but his mother disapproves, fearing Izumi could hinder his success in "a world with sound." Reiko insists Akito focus on his piano, but her expectations burden him. Then Akito begins to question his mother's attitude towards life as well as his own when he discovers something new about her.
