Sat-chan Tadashi-chan: Sengo minshu-teki dokuritsu pro funtō-ki.

After the war, many filmmakers were expelled from the Japanese film industry due to the Toho Dispute and the Red Purge. Amid such circumstances, there were people who set up their own independent production companies and embarked on film production without relying on corporations. This documentary film focuses on the passionate "spirit of film" of directors such as Satsuo Yamamoto and Tadashi Imai, who, despite many hardships, produced a succession of masterpieces overflowing with humanism and rebellious spirit.
