Duclos's son, a worldly gangster, is compromised in a case of which he is innocent. The proof of this innocence is in the hands of a "competitor", the Marquis de Chemantel de Beauvoiron, a misguided aristocrat. He asked for $ 10 million to cede the document. Duclos will then imagine Chemantel contracting $ 10 million in life insurance for his son. As he discovered in Rome a tramp, a look-alike of the marquis, he will bring this man to Paris and arrange for him to die accidentally.
