In 1964, Momoko came by herself to Tokyo from her hometown. She met Shūzō and married him. They raised two children together, but Shūzō suddenly passes away. Momoko is dumbfounded by being alone again. She begins to go to the library and borrows books. This changes her life.
Set in Tokyo seven years after the end of WWII, this surreal story revolves around the dreams and realities of a young boy who strays into a strange mansion while out chasing fliers dropped by a small aeroplane. Confined inside are four adults suffering from an incurable disease ('porphyria', which the author avoids specifying by name in the screenplay) which prevents them from having exposure to the sun.
A mind in the city looks inwards, and escapes into the rabbit's domain.
