Heaven, Hell is a feature-length documentary dealing with human diversity that doesn’t necessarily lead to Hell even though it might seem like it from the outsider’s point of view. It is an attempt to defend even the very extreme views of freedom if such views are well-founded and lead to new levels of human understanding. The film profiles people who have found pleasure in pain and decided not to conceal this passion, or at least not to suppress and deny it any longer. These people either inflict pain or demand it from others, but they do not force anyone to do anything. This private society is often labelled by its members as BDSM.
