Watch Sadisflix. In 1983, the director’s 24-year-old sister developed symptoms of schizophrenia. Her parents couldn’t accept it—refusing to seek treatment for their sick child, they confined her to their house, to the point of even fixing a padlock on the front door to lock her in. Her younger brother, suspicious of his parents’ actions, began filming the family in an effort to openly question them. A family conflict that lasted over twenty years.
