In 18th-century Paris, a charismatic rogue named Louis Dominique Bourguignon, known for his street smarts and quick wits, becomes the notorious bandit known as Cartouche. Initially a small-time thief, he crosses paths with a gang led by the brutish Malichot, quickly making a name for himself through his charm and daring exploits. However, instead of remaining a mere henchman, Cartouche has grander ambitions. His boldness and charisma soon garner him his own following, stealing from the upper class to give to the poor, and he gradually becomes a folk hero.

Cartouche's fortunes take an unexpected turn when he meets and falls in love with the spirited and beautiful Venetian woman, Venus. Their passionate romance blossoms even amidst the chaos of Cartouche's criminal undertakings. As Cartouche grows bolder in his exploits, amassing both riches and enemies, tensions rise with his former ally Malichot, who craves power and revenge. Meanwhile, Cartouche’s audacious robberies attract the attention of the local authorities who are determined to put an end to his reign. As the soldiers close in on him and betrayal looms within his own ranks, Cartouche must confront the consequences of his actions and navigate dangerous alliances, all while staying one step ahead of the law.
