Assane Diop has spent years turning deception into an art form. His disguises, elaborate plans and ability to predict other people's behavior made him a formidable thief. Now someone else has learned to exploit precisely those qualities.
All eight episodes of Lupin Part 4 are available on Netflix as of October 23, 2026. The new installment begins four years after the previous story ended, with Assane still in prison following his decision to surrender to the authorities.
His intention is straightforward: finish his sentence, leave his criminal past behind and fulfill a promise to his son Raoul. They are supposed to travel to Senegal together and reconnect with their family.
Then someone announces a series of simultaneous museum robberies using the Lupin name.
The thefts go ahead despite increased security. Assane insists that he has nothing to do with them, yet surveillance footage apparently places him at one of the crime scenes. Captain Sofia Belkacem is seriously injured during one robbery, further raising the stakes.
Suddenly, the character who spent three installments manipulating appearances must confront an enemy capable of doing the same thing to him.
An escape that undermines everything Assane wanted
Assane's decision to surrender at the end of Part 3 was meant to protect his family. Rather than continue living through increasingly elaborate deceptions, he accepted imprisonment as the price of giving Claire, Raoul and the people close to him some measure of stability.
That sacrifice now looks considerably less secure. His son is growing older, the family relationships have changed, and the prospect of traveling to Senegal represents more than a holiday. It is part of the ordinary life Assane hoped might still be possible.
The copycat robberies destroy that carefully imagined future. With evidence mounting against him, Assane decides that clearing his name requires a return to the very methods he intended to abandon.
His solution is to escape from prison and investigate the person responsible for the crimes.
The contradiction is central to the new story. Assane needs to commit another spectacular escape to demonstrate that he is innocent of the crimes attributed to him.
Familiar faces return, but time has changed the family
Omar Sy is again joined by Ludivine Sagnier as Claire and Antoine Gouy as Benjamin Ferel, Assane's longtime friend and accomplice. Soufiane Guerrab returns as police investigator Youssef Guédira, while Shirine Boutella reprises her role as Sofia Belkacem.
Benjamin's presence is particularly important given the central mystery. His knowledge of Assane's methods and history makes him an indispensable ally when someone begins imitating the gentleman thief's identity.
One significant casting change concerns Raoul. Théo Christine now portrays Assane's son, who has grown considerably during his father's imprisonment.
That passage of time gives the father-son relationship a different shape. Raoul is approaching adulthood, and the promise of a shared future carries consequences that cannot simply be postponed by another ingenious plan.
Laïka Blanc-Francard also joins the cast as Adèle. Netflix provided additional details about the characters in a cast guide published on October 27, shortly after the season's release.
For a series largely defined by Assane's ability to outsmart everyone around him, these personal relationships remain essential. The character can invent identities almost at will, but he cannot control how much his family changes while he is absent.
The most dangerous disguise is Assane's own face
The copycat premise is an intriguing extension of Lupin's established mythology.
Assane built his criminal identity around the stories of Arsène Lupin, the gentleman thief created by Maurice Leblanc. He studied their elaborate deceptions and transformed fictional techniques into modern heists, often using them to confront injustices connected to his father's past.
That literary inheritance now becomes a liability. Someone has taken the identity that Assane borrowed and turned it into a means of framing him.
The museum robberies have been publicly announced under the Lupin name, creating expectations that the real Assane would be responsible. When apparently convincing evidence emerges, his reputation does much of the impostor's work.
It is an effective reversal for a story that has always depended on the gap between appearance and reality. Assane previously exploited what others assumed about him. His new enemy exploits what everyone believes they already know.
The situation also raises the stakes for Youssef Guédira, whose familiarity with Lupin's methods has long influenced his investigations. An opponent who understands those methods introduces an additional layer of uncertainty.
A French production with an expanded creative team
Part 4 consists of eight episodes directed by Édouard Salier, Everardo Gout and Hugo Gélin. The scripts are credited to Mathilde Arnaud, Jean-Yves Arnaud, Tigran Rosine and Florent Meyer.
George Kay remains the series' creator alongside François Uzan, with contributions from Marie Roussin, Florent Meyer and Tigran Rosine. Omar Sy and Louis Leterrier serve as showrunners, while Gaumont produces the series with the participation of Carrousel Studios.
The project retains the fundamental distinction that has shaped Lupin since its debut in January 2021. Omar Sy does not play Maurice Leblanc's original Arsène Lupin. Assane Diop is a contemporary character who has absorbed the books and turned their hero into a personal inspiration.
That premise gives the writers room to explore modern questions of surveillance, reputation and technological manipulation without abandoning the classic pleasures of a gentleman-thief adventure.
All eight episodes are available now
Netflix released the complete fourth part on October 23 rather than dividing the story into weekly installments. The new episodes therefore follow the streaming service's established binge-release approach for Lupin.
The installment arrives three years after Part 3, which premiered in October 2023 and ended with Assane behind bars. That ending was not merely a temporary obstacle: the new storyline treats his imprisonment and the resulting separation from his family as important developments.
The larger mystery now revolves around the identity and motives of the person carrying out robberies under his name. Assane must expose the impostor while dealing with the consequences of escaping prison and once again becoming a fugitive.
For a man determined to retire from the role of Lupin, discovering that someone else has taken it over may be the most personal challenge yet.
