Lupin's Daughter Steals Crown Jewels, Raoul Betrays Him

Lupin Part 4, released on October 23, 2026, picks up four years after the previous season, with Omar Sy returning as Assane.

Assane, nearing early release from prison and planning a move to Senegal with his son Raoul, finds himself the prime suspect when a copycat thief, posing as Lupin, orchestrates major robberies. He escapes prison to uncover the truth behind these acts.

The copycat is revealed to be Adèle, Assane's daughter, who is seeking the legendary treasure of Louis XVI's French Crown Jewels. Twenty years prior, Juliette became pregnant with Adèle but was led to believe the baby was stillborn. The treasure is protected by powerful families, including the Pellegrinis.

To end the threat, Assane devises a plan to steal the treasure himself. The heist involves tampering with the Seine's flood mechanisms to force the Guardians to relocate the jewels. Juliette, disguised as corrupt cop Korvin, absconds with the treasure while Assane creates a diversion.

However, the handover goes awry. Pellegrini contacts Assane, demanding the treasure. Adèle is captured with a ticking device, but Raoul's lack of fear suggests he is involved. Years of Assane's broken promises have led Raoul to feel abandoned, especially witnessing Assane's bond with Adèle. He aligns with Pellegrini, offering help in exchange for leaving Malaysia.

During the tense standoff, Raoul confronts Assane, demanding he choose between him and Adèle. Assane refuses, and Raoul, perceiving this as a choice for Adèle, departs with Pellegrini. Sofia threatens Raoul, prompting Assane to jump in front of the bullet, taking a direct hit to the chest. His survival remains uncertain as Raoul watches the helicopter depart, while Assane's family rushes to his aid.
