Under a False Name (2004)

After reading a postcard that her mother let go in the wind, a woman learns that she has a twin.

The small Norman village of Allouville is proud of its thousand-year-old oak tree. But one day, a project of enlargement threatens the tree. The deputy Charles Crétois was keen on this project, which allowed him to continue the speculation he had been indulging in on certain lands. He is supported by the mayor of Allouville to whom he promised the Legion of Honor. But the whole village protests: they want to save the oak tree.

Arsénio Lupin, o multifacetado ladrão cavalheiro, rouba duas obras-primas do Presidente do Conselho. Algum tempo depois, fazendo-se passar por Monsieur Gilles, um viticultor que está se casando com sua única filha, ele pede a vários joalheiros que venham a sua mansão e lhes rouba suas pedras preciosas. As próximas vítimas de André Laroche (a nova identidade de Lupin) serão ninguém menos que um marajá e o próprio Kaiser Wilhelm II.
