Lupin Season 4 (Part 4): Release Date, Cast, Plot & Everything We Know About the Netflix Return

Four years into his prison sentence, Assane Diop is forced to become Lupin once more to unmask a copycat thief.

Search interest in Lupin has detonated across every language Netflix streams in — "lupin saison 4" in France, "lupin staffel 4" in Germany, "lupin 4 temporada" in Spain, "quando esce lupin 4" in Italy, "lupin yeni sezon ne zaman" in Turkey. The reason is simple: after a three-year wait, the world's most-watched French-language series is finally back.

Lupin Part 4 premieres globally on Netflix on Friday, October 23, 2026, with all eight episodes arriving at once. Omar Sy returns as Assane Diop, the gentleman thief inspired by Maurice Leblanc's classic novels — and this time, the master of disguise is the one being impersonated.

Where Did Part 3 Leave Assane Diop?

Part 3 (released October 2023) saw Assane steal the Black Pearl, fake his own death, win over the French public and save his estranged mother's life. But his elaborate schemes to give his family a quiet life collapsed — and in the final twist, Assane surrendered himself to the police, accepting imprisonment as the only way to keep Claire and Raoul safe.

The last shot was the series' cruellest cliffhanger: alone in his cell with his Arsène Lupin books, Assane receives an envelope from a neighbouring inmate — a photograph of himself as a teenager holding Cagliostro's Revenge. The sender was his arch-nemesis, Hubert Pellegrini, locked up in the same prison.

What Is Lupin Season 4 About?

Netflix's official synopsis picks up the story four years later. Assane is still behind bars — but he has made his peace with it. Lupin is no more: he intends to serve out his sentence quietly and keep the promise he made to his son to travel to Senegal and meet their extended family.

Then a mysterious announcement signed by "Lupin" shatters everything. Multiple museums are targeted in simultaneous heists — and despite heightened security, every single one succeeds. Assane proclaims his innocence, but everything points to him. Security camera footage even shows him inside one of the museums during a robbery in which Captain Belkacem is seriously injured.

To prove his innocence and unmask the copycat, Assane has no choice: he must escape, and he must become Lupin once more.

The Hook

After three seasons of Assane impersonating everyone else, Part 4 flips the premise — someone is impersonating him, committing crimes in his name and framing him for the fallout. It is the cleanest high-concept reversal the series has attempted.

Who Is in the Cast of Lupin Part 4?

Omar Sy — Assane Diop

The gentleman thief himself, who also serves as co-showrunner alongside Louis Leterrier. Sy told Netflix that Lupin "is an extraordinary plaything" he finds "great joy" in every time.

Ludivine Sagnier — Claire

Assane's wife, caught between her love for him and her determination to protect their son from his double life.

Antoine Gouy — Benjamin Ferel

Assane's loyal best friend, accomplice and master forger.

Soufiane Guerrab — Youssef Guédira

The detective whose obsession with the Arsène Lupin books makes him Assane's most dangerous — and most sympathetic — pursuer.

Shirine Boutella — Sofia Belkacem

The principled officer whose injury during the museum heists raises the stakes of the copycat investigation.

Théo Christine — Raoul Diop

Takes over the role of Assane and Claire's son from Etan Simon, playing an older Raoul after the four-year time jump. Sy, as co-showrunner, personally recruited Christine, known for Suprêmes, Vermines and Vivre.

Laïka Blanc-Francard — New to Part 4

The second confirmed newcomer, similarly under wraps ahead of release.

One notable change: Etan Simon, who played Raoul in Parts 1–3, has been recast. Théo Christine now plays the character as an older teenager, reflecting the four-year time jump between Parts 3 and 4 — a casting switch Netflix never formally announced, but which Christine himself has confirmed in the run-up to the premiere.

Who Makes Lupin?

The series was created by George Kay in collaboration with François Uzan, with the participation of Marie Roussin, Florent Meyer and Tigran Rosine. Sy and Leterrier serve as showrunners. Part 4 was written by Mathilde Arnaud, Jean-Yves Arnaud, Tigran Rosine, Florent Meyer and Pennda Ba, and directed by Édouard Salier, Everardo Gout and Hugo Gélin.

Production on the eight-episode instalment began in May 2025 and wrapped in September 2025, filmed once again primarily in Paris. The series is produced by Gaumont in collaboration with Carrousel Studios, in which Omar Sy is a partner, and remains freely inspired by Maurice Leblanc's Arsène Lupin stories from the early 20th century.

Why Lupin Season 4 Is Driving Global Search Traffic

The Three-Year Cliff

Part 3 ended in October 2023, making this the longest gap between Lupin instalments yet. A fandom used to devouring the show in one weekend has spent three years debating who set Assane up — and whether Hubert Pellegrini engineered his imprisonment from the inside.

A Non-English Flagship

Lupin has drawn well over 100 million viewers since its 2021 debut and stands as one of the most successful non-English productions in Netflix history — proof that a French-language heist series can outdraw most Hollywood tentpoles. Every new part is a global streaming event by default.

The Premiere Circuit

Netflix held the Part 4 premiere in Paris on October 21, 2026, two days before release, with Omar Sy — now a co-showrunner as well as star — telling press he leveraged that new role to personally recruit Théo Christine. The rollout has kept the copycat's identity tightly under wraps, which only feeds the speculation cycle.

The Copycat Premise

The trailer's reveal — a rival thief committing museum heists under the Lupin name while Assane rots in prison — gives the season an instant engine: a mystery box (who is the copycat?), a redemption arc (can Assane prove he's changed?) and the franchise's signature puzzle-box heists, all at once.

Lupin Season 4 FAQ

When does Lupin Season 4 come out?

Part 4 premieres globally on Netflix on Friday, October 23, 2026.

How many episodes are in Lupin Season 4?

The season contains eight episodes of approximately 45 minutes each, all released at once.

Is there a trailer for Lupin Part 4?

Yes. Netflix released the official Part 4 trailer on September 14, 2026, revealing the copycat mystery at the center of the season.

What is Lupin Season 4 about?

Four years into his prison sentence, Assane Diop plans to serve his time and reunite with his family in Senegal. When a copycat "Lupin" pulls off simultaneous museum heists and frames him — with Captain Belkacem injured in one of the robberies — Assane must escape and unmask the impostor.

Who is in the cast of Lupin Part 4?

Omar Sy returns alongside Ludivine Sagnier, Antoine Gouy, Soufiane Guerrab and Shirine Boutella. Théo Christine joins as the recast, older Raoul Diop, and Laïka Blanc-Francard takes on a still-unrevealed role.

Is Hubert Pellegrini back in Season 4?

Part 3 ended with the reveal that Pellegrini was Assane's fellow inmate, strongly implying a continuing role. Trade reports on the Part 4 announcement have listed Hervé Pierre among the returning cast, although Netflix's official Tudum cast list for Part 4 does not spotlight him — so expect the arch-nemesis to loom over the season, even if Netflix is keeping his exact role quiet.

Is Raoul recast in Lupin Season 4?

Yes. Etan Simon, who played Raoul in Parts 1–3, has been replaced by Théo Christine, who plays an older version of the character consistent with the four-year time jump.

Do I need to watch Parts 1–3 before Part 4?

Strongly recommended. The copycat storyline leans on everything Assane has done as Lupin, and the prison fallout is a direct continuation of Part 3's cliffhanger.

Will there be a Lupin Part 5?

Netflix has not announced a fifth installment. Given the series' status as one of the platform's biggest non-English hits, renewal will likely depend on Part 4's global performance.

Where can I watch Lupin?

All four parts stream exclusively on Netflix, with subtitles and dubs available in most regions.
