Piétrefond, a historian, claims to have discovered in the archives that a humble locksmith Louis Mennechain is really descendant of the guillotined monarch of France Louis XVI. Louis is taken up by an attractive duchess and her friends, and begins to become dazzled before his new status. Piétrefond reveals to him that the whole thing is really a scam to make money, and Louis returns to his fiancée Anna and his previous existence. Yet doubts continue in his mind about his possible royal heritage.
