Trailer for the documentary Heaven, Hell.
Heaven, Hell is an attempt to defend even very extreme notions of freedom if such notions are well-founded and lead to new horizons of human understanding. The film portrays people who have found pleasure in pain and decided not to hide this passion, or at least not to suppress and deny it any more. These people either inflict pain or demand it from others, but they do not force anyone to do anything. This closed society is often labelled by its members as BDSM.
