Well, this unknown but genius horror film had a deep and real beyond story, including the mystery of the screenplay, very real feeling of dead world. I can compare this film with Lucio Fulci's last "The door to the silence" of the same year. A detective is working on a strange suicide story and meets strange people who tells about "forzi"- some beyond creatures taking away people beyond. The hero was prohibited to say the words "The life is wonderful and nice". Every time he said that accident happen. Bad ending . A lot of cemeteries, super sound-effects, true story and masterpiece music.
