Based on the true story of France's most infamous killer, Pierre Lacenaire. The film begins with Lacenaire in prison, writing his memoirs, receiving his admirers, and awaiting his execution (in 1836). A series of flashbacks detail his life and the supposed social clime which hindered his better instincts and turned him to the criminal life. However, Auteuil has such a wonderful time playing the charming bad guy that any blame to society fails to convince. In French with English subtitles.
