A man teaches calligraphy at a girls' high school. His son begins to work as a head teacher at the same school after finishing educational study in America. Many conflicts take place between them because the father is very stubborn. But he is proud of his son who outranks him. The son changes his pay envelope with father's one on every salary day to keep father's face, but it comes to light. The family members are happy and cheerful as usual.
