The film is about a French town where a number of citizens receive anonymous letters containing libelous information, particularly targeting a doctor accused of providing abortion services.
In a small French town identified as "anywhere", anonymous poison pen letters are sent by somebody signing as "Le Corbeau" (the Raven).
The situation becomes increasingly serious when a patient of the hospital commits suicide with his straight razor after the Raven writes to him that his cancer is terminal.
Just as the ambulance takes Laura away, Germain returns to find Dr. Vorzet dead at his desk, his throat cut by the cancer patient's mother as he was writing the Raven's final, triumphant letter.
Writer Joseph Kessel later criticised the film's Continental origins, noting Le Corbeau was funded by the Germans, and in that context could be seen as a statement on French corruption.
[1] In 1947, the film was released commercially, with writer Henri Jeanson praising it as a major piece in French cinema, arguing it was repulsive, but, when compared to reality, became nearly romantic.
[5] Despite criticising its origins, Joseph Kessel, writing in response to Jeanson, said that Le Corbeau was indisputably a remarkable film.
In 2006, the film enjoyed a resurgence in popularity in Paris after the Clearstream affair, in which anonymous letters accused French politicians of having hidden bank accounts.
