Masao Adachi's Datai (Abortion) is about a crazy gynaecologist who wants to liberate mankind from sexual problems by radically separating sex on the one hand and reproduction, which should be left to artificial wombs, on the other. For the opening scene Adachi used a birth scene from an older 16mm sex education film, either a pre-war osan eiga or a post-war basukon eiga. Datai is Adachi's first pink eiga movie.
