Mario Mieli was one of the most surprising figures of the great season of the 70s: intellectual, writer, performer, provocateur, but above all an activist for the rights of homosexuals and author of a cornerstone of gender and queer studies such as Elements of homosexual criticism. This documentary film in the form of a collection of materials and "notes" in five chapters (Poetry, Movement, Theatre, Alchemy, Death) shows the numerous and incredible facets of a unique personality in the Italian panorama, through the stories of ten friends and witnesses and a large number of audio and video materials, partly unpublished and shown here for the first time.
