Middle-aged alcoholic Gin, teenage runaway Miyuki and former drag queen Hana are a trio of homeless people surviving as a makeshift family on the streets of Tokyo. While rummaging in the trash for food on Christmas Eve, they stumble upon an abandoned newborn baby in a trash bin. With only a handful of clues to the baby's identity, the three misfits search the streets of Tokyo for help in returning the baby to its parents.
