On Christmas Day, on the streets of Tokyo, three homeless people - Gin, a forty-something year old man, Miyuki, a teenage girl who has run away from her family, and Hana - a religious transvestite who dreams of bearing a child - find an abandoned baby in the snow. Hana, who was also abandoned as a child, takes a passionate interest in the infant's wellbeing, and reluctantly at first, the others join her as they seek to find the child's mother.
