The crazy story of Mineshaft, a hardcore gay club that has been open in Marseille since 1967, with the presentation of a montage based on old BDSM porn VHS tapes. In the presence of the bar's managers, Marc and Angelo, and a number of regulars, this film recounts a genealogy of S&M images, opening up an exchange on the history of the place, and of hard sexuality through the generations in Marseille.
