Jacques Prémont-Solène is a degenerate gambler and his losses at baccarat have bankrupted his lover, Laure Maresco. When he steals four hundred thousand francs and loses that at the gambling tables, he flees to the United States, and Nathalie takes the blame. Twenty years later, she has a flourishing career as a nightclub singer, but their son is just as inept a gambler as his father had been.
