The 1960s-’70s marked the Golden Age of Wakamatsu Productions, founded by revolutionary auteur Koji Wakamatsu (Caterpillar) and staffed (for free) with radical young artists like avant-garde filmmaker Masao Adachi, cinematographer Hideo Ito, and scriptwriter Haruhiko Arai. Kazuya Shiraishi (The Blood of Wolves) also cut his teeth making low-budget exploitation pictures at the company, and has now directed this rambunctious, fact-based account of one young dreamer, Megumi Yoshizumi, who joins Wakamatsu in 1969 to make pinku eiga (softcore porn). As she struggles to fit into the testosterone-heavy “family,” and to find her own voice, Megumi’s life becomes equal parts heroic and tragic.
