Heartbeat Detector on AllMovie

As a Parisian petrochemical company forges on into the 21st century, the in-house human resources psychologist leads a probe that proves the ghosts of the previous century still hold sway over current events in director Nicolas Klotz's labyrinthine drama. Simon (Mathieu Amalric) is a human resources worker who has spent the last seven years working at the Paris branch of a powerful German-based company called SC Farb. In addition to assessing the hiring and firing practices of the company, Simon was also charged with the task of conducting motivational workshops. When Assistant Director Karl Rose (Jean-Pierre Kalfon) implores Simon to conduct a clandestine assessment of firm director Mathias Jüst's (Michael Lonsdale) mental health after rumors of erratic behavior begin to circulate in the German head office, the shrewd human resources worker forms a factory orchestra as a means of stealthily gauging the stability of his violin-playing subject. Later, a comprehensive investigation of company archives and anonymous letters begin to snake ominously back in time to the darkest days of World War II.
