Omar Sy returns as Assane Diop on Friday 23 October. A copycat thief, eight new episodes and a mystery that begins with the gentleman thief still behind bars.
Assane Diop has spent three parts borrowing identities. Now someone is borrowing his. The next chapter of Lupin opens with France’s most resourceful gentleman thief in prison, only for a string of museum robberies to carry a name the police know all too well: Lupin.
Omar Sy returns to the French-language Netflix thriller on Friday 23 October 2026, three years after Part 3. The new mystery promises another contest of nerve and deception, but it starts in an unfamiliar position for Assane. This time, he is the one insisting that appearances are misleading.
When is Lupin Part 4 on Netflix UK?
Friday 23 October 2026 is the confirmed release date. Netflix includes the series in its October 2026 release guide, while its Part 4 announcement says all eight episodes will arrive together. There is no weekly release schedule to follow.
UK viewers can find the series on Netflix’s UK programme page. Parts 1–3 are available there for anyone wanting a refresher before the new chapter. Netflix has not specified a UK launch hour in the official release material, so a precise midnight or morning availability claim would be guesswork.
A Netflix subscription is required. Our report on the latest Netflix UK price changes is worth checking if you are returning to the service after a break.
Someone else is calling themselves Lupin
Four years have passed within the story since the end of Part 3. Assane remains in prison and has decided to put the Lupin persona behind him. He wants to serve his sentence and keep a promise to his son: to meet their family in Senegal.
Then comes an announcement signed ‘Lupin’. Several museums are to be robbed at the same time. Security is tightened, yet the thefts go ahead — and the evidence points towards Assane. He denies any involvement, but his reputation as a master of elaborate cons hardly works in his favour.
That is the intriguing reversal at the centre of Netflix’s official synopsis. Assane has relied on getting other people to believe the wrong thing. Now he has to convince them that what appears to be his handiwork belongs to somebody else. The full synopsis goes further, but the identity of the copycat and the mechanics of the robberies are better left for the episodes.
A quick catch-up before Part 4
The original Lupin is about more than a man with a talent for disguises. Assane takes inspiration from Arsène Lupin, the gentleman thief created by French novelist Maurice Leblanc, while pursuing the truth about his father Babakar. His father was framed for stealing a valuable necklace, and Assane’s schemes gradually expose the wealthy Pellegrini family’s role in what happened.
Parts 1 and 2 bring Assane into conflict with the police and the people who profited from his father’s downfall. His childhood friend Benjamin helps him put plans together, while investigator Youssef Guédira begins to see the Arsène Lupin references running through the crimes. Claire and their son Raoul are never far from the consequences.
Part 3 turns up the pressure on Assane’s family life. There is another audacious theft, an attempt to escape his own notoriety and danger for those closest to him. In the end, Assane gives himself up to protect them. That decision explains the prison setting of Part 4 — a detail Netflix has already made public, rather than a new-episode spoiler.
If it has been a while since you watched, the final episode of Part 3 is the best place to pick up the emotional threads. First-time viewers will get much more from starting at Part 1: the old loyalties and grudges matter just as much as the clever escapes.
Who is returning for Lupin Part 4?
Omar Sy is back as Assane Diop, alongside a familiar supporting cast. Netflix has confirmed Ludivine Sagnier, Antoine Gouy, Soufiane Guerrab, Shirine Boutella, Théo Christine and Laïka Blanc-Francard for the new part.
Sagnier plays Claire, Gouy is Benjamin, Guerrab returns as Guédira and Boutella plays Sofia Belkacem. Christine plays Assane and Claire’s son, Raoul. Netflix has listed Blanc-Francard among the cast without spelling out her part in the new mystery, so there is no reason to speculate about a character reveal.
The creative team also retains important names from earlier instalments. George Kay created Lupin in collaboration with François Uzan, with Marie Roussin, Florent Meyer and Tigran Rosine credited as contributors. Sy and Louis Leterrier are named as showrunners, and Gaumont produces the series in collaboration with Carrousel Studios. The cast and creative continuity should help the fourth part feel like a continuation rather than a fresh start.
Watch the official Part 4 trailer
The official Lupin Part 4 trailer is available on Netflix’s verified YouTube channel. It sets out the copycat problem and shows the predicament Assane faces after his decision to surrender. Viewers who prefer their mysteries completely unspoilt may want to save it until after the opening episode.
There is also a recap of Parts 1 and 2 on Netflix’s UK programme page, alongside trailers for the earlier chapters. It is useful if you remember the major heists but have forgotten how Assane’s relationships with Claire, Benjamin and the police developed.
Tech Torque Verdict
A copycat calling themselves Lupin is a strong way to turn the series’ central idea against its hero. Assane’s greatest advantage has always been his ability to decide what others see. A rival using the same tricks, and his name, gives the new part an immediate personal stake.
Whether the eight episodes deliver on that promise remains to be seen. We have not screened Part 4, so this is a release preview, not a viewing review. What is confirmed is appealing enough for returning fans: Omar Sy is back, the principal cast returns, and the mystery begins on Netflix UK on 23 October.
