In this version set in the 1930s and 1940s, Arsène Lupin (François Dunoyer) travels across Europe and sometimes beyond, always caught between two worlds: that of hushed salons and that of masterful heists. Each episode is a standalone adventure, but together they paint a portrait of a mature gentleman thief, more strategic than ever, who toys with the powerful, protects the weak, and always stays one step ahead of the police... and his enemies.
