Ok so I remember a friend of mine showing me this strange trailer involving a new German (Austrian?) film.  The trailer was really strange and sexual in natured and the last scene of the trailer involved this guy walking into a dark basement that appeared to be a S&M sex room.  It caught my attention and looked so strange/scary but I can’t for the life of me remember what it was called and I can’t remember much else about it except it was really strange.  Needless to say when I google strange German sex movies I get some interesting search results.  lol  I think this film was made in 2014,15, or 16 not sure.  Anyone know anything about this film?
