 In the 30s, a low middle-class family composed of the father (Tatsuo Saito), the mother (Mitsuko Yoshikawa) and two little sons (Hideo Sugawara and Tomio Aoki) has just moved to a suburb of Tokyo. The two brothers have some sort of adaptation problem with the kids in their neighborhood, but they feel protected with their beloved father, and they become leaders of the gang. Their father is a clerk in an office, and his director lives in the same neighborhood, and he tries to be promoted in his job being a servile flatterer of his boss. One night, the boys find that his father has a silly behavior in his job to please his boss, and they lose the respect for their father, questioning him why he can not be the director of the company.
