In Paris, in the middle of the 19th century, the Comte de Chamery died of poisoning, leaving a considerable fortune to his long-dead son. Sir William, the count's murderer, hires a young rogue, Rocambole, to pretend to be the deceased's son. The two accomplices have the Count's fortune handed over to them. But their trickery is discovered by an intriguer, Baccarat, who finds the real Count of Chamery, a young painter without fortune, in love with Carmen de Montevecchio. Rocambole, who stops at nothing, kills Sir William, gets rid of Armand and makes Carmen love him. But Baccarat is determined not to let him continue his villainies.
