Young Émile (Jacques Perrin) couldn't stand to see a lonely lady looking sad... so he took it upon himself to choke them with his crocheted white scarf. As determined police inspector Dangret (Julien Guiomar) poses as a pop criminologist in order to flush him out via the media, the killer finds a worthy foil that he can dare to stop him. Paul Vecchiali's uncovered psychosexual giallo also stars Eva Simonet, Paul Barge, Jacqueline Danno, Hélène Surgère. 93 min.
