Sur le seuil

  • A film by Éric Tessier
  • Featured-length - 2003

Local media is in a frenzy covering an inexplicable massacre that has left only questions and no answers. The same day, Thomas Roy, an internationally renowned horror novelist, attempts suicide after having cut off all of his fingers. At first, the two events appear to be unrelated. But then, Dr. Paul Lacasse, a burned out psychiatrist, is given the novelist’s case. Encouraged by his young colleague, Jeanne (a fan of Roy’s books), Paul leads the investigation of his supposedly “normal” patient’s past.

Tabloid columnist Monette’s research helps Dr. Lacasse uncover extremely disturbing information that challenges his beliefs, both personal and professional. By attempting to put together the mind-blogging fragments of his patient’s past in order to better care for him, Paul is dragged into a chain of events with terrifying consequences.
