Inspired by the adventures of Arsène Lupin, gentleman thief Assane Diop sets out to avenge his father for an injustice inflicted by a wealthy family.
Years after a tragic injustice, Assane seeks to settle a score — and a debt — by stealing a diamond necklace, but the heist takes an unexpected turn.
Assane hatches a plot to contact Comet, an inmate who steers him to a clue about Babakar's demise. Anne Pellegrini comes clean about the past.
Assane confronts Commissioner Dumont and plants a decoy to divert the police. Hubert Pellegrini's connection to Babakar's fate comes to light.
To retrieve incriminating evidence on Hubert, Assane enlists the help of a journalist. Officer Guédira connects the dots around the Louvre heist.
