Japanese mystery thriller.

Jidai-geki by Kiyoshi Saeki

Two young girls, Nobiko and Tomiko, go to the same school. The less fortunate girl Nobiko is one of the top students, while the rich girl Tomiko is not. At one time Tomiko's father was quite fond of Nobuko's mother.

In postwar Japan, two sisters—a film studio script girl and a revue dancer—become swept up in the growing labor movement when workers around them strike for better conditions. As their conservative father opposes their activism, his own dismissal forces him to confront the realities of class struggle and join their fight for a fairer future. Now considered a lost film, Those Who Make Tomorrow was produced by Toho to promote unionization during Japan’s Allied Occupation.
