Those Who Make Tomorrow - Akira Kurosawa, Hideo Sekigawa, Kajirō Yamamoto

Two sisters, one a dancer and the other a script supervisor at a big movie studio, become embroiled in union activities when a strike is called in sympathy with striking railroad workers, one of whom boards with the sisters and their parents. The girls' father argues with them about their strike, but finds his views changing when he himself loses his job.
