Follows a family man who meets women through lonely-hearts ads.

During the World War I, in France, the middle-aged, bearded trader of furniture Henri-Desiré Landru is married with four children. He spends a few time with his family since he has a secret life. He publishes advertisements looking for lonely wealthy women and seduces them with his politeness. Then he travels with them to a house in Gambais, where he kills them and burns them to the ashes in his stove. Then he returns home with money claiming that he earned in business trips. When he meets the beautiful Fernande Segret, she becomes his mistress. He kills at least eleven women until the day the sister of one of his victims recognizes him. But the police need to find evidence but there is no body.—Claudio Carvalho, Rio de Janeiro, Brazil
