A repeat featuring the same gentleman burglar, Signe Arsene Lupin is the effective, leisurely told sequel to the 1956 Les Aventures d'Arsene Lupin that started it all. The burglar of the title, played by Robert Lamoureux, has just been released from military service after World War I and is hot on the trail of a 15th-century treasure. He is convinced that the objet d'art is hidden somewhere in three Flemish miniature works but he is not alone in his quest. A female counterpart, Aurelia (Alida Valli) -- and how attractive she is -- wants exactly the same treasure. Sophisticated and debonair, Lupin is not above engaging in a little romance and deception in order to achieve his lucrative ends.
