Three sisters - Sachi, Yoshino and Chika - live together in the city of Kamakura, Japan. When their father - absent from the family home for the last 15 years - dies, they travel to the countryside for his funeral and meet their shy, teenage half-sister. Bonding quickly with the orphaned Suzu, they invite her to live with them. Suzu eagerly agrees and a new life of joyful discovery begins for the four siblings.
