An Inn in Tokyo, 1935

Kihachi, an unemployed worker, wanders around the industrial flatlands of Tokyo's Koto district with his two young sons, Zenko and Masako. He is unable to find a job and has to rely on his sons catching stray dogs to earn reward money for their meals. As days go by, Kihachi and the boys no longer have enough money to stay at an inn for the night. Luckily for him, he encounters an old friend, Otsune, who finds him a job and allows them to stay at her eatery house.
