The story follows professional thief Assane Diop, the only son of an immigrant from Senegal who had come to France to seek a better life for his child. Assane’s father is framed for the theft of an expensive diamond necklace by his employer, the wealthy and powerful Hubert Pellegrini, and hangs himself in his prison cell out of shame, leaving the teenage Assane an orphan. Twenty-five years later, inspired by a book about gentleman thief Arsène Lupin his father had given him on his birthday, Assane sets out to get revenge on the Pellegrini family, using his charisma and mastery of thievery, subterfuge, and disguise to expose Hubert’s crimes.
