One of several versions of a steamy novel by Eugene Sue, Les Mystères de Paris is set at the turn of the 20th century and begins when the carriage of Count Rodolphe (Jean Marais) runs over a man and as he dies, the Count vows to help his poor, orphaned daughter Marie (Jill Haworth). And so the Count penetrates the "thieves' quarter" in Paris looking for Marie, and he is emotionally overcome by the poverty he sees everywhere. After he meets Marie, he is attracted to her -- but then she is kidnapped and eventually, the Count learns the truth about her paternity.
