Lupin Part 4: Museums, Jewels, and Luxury Locations of the Season

Netflix chose its formula carefully: “Watch your diamonds”. This is how the platform presented, on 14 September 2026, the trailer for the fourth part of Lupin, the series produced by Gaumont that Netflix counts among its most popular non-English language productions. Here’s what the season promises to jewel enthusiasts, and what previous seasons had already stolen.

What Netflix has revealed about the plot

The official synopsis published by Netflix is just a few lines long. Four years after the end of Part 3, Assane Diop is still in prison. For him, Lupin no longer exists: he wants to serve his sentence and keep the promise he made to his son, to go and meet their family in Senegal. A mysterious announcement signed “Lupin” warns that several museums will be robbed at the same time. Despite heightened security, the thefts take place. A camera even shows Assane in one of them, during a heist where Captain Belkacem is seriously injured. To prove his innocence and unmask the imitator, he will have to escape and once again don the costume.

“I often say that Lupin is an extraordinary toy,” Omar Sy confides to Netflix. He reunites with Ludivine Sagnier, Antoine Gouy, Soufiane Guerrab, and Shirine Boutella, joined by Théo Christine and Laïka Blanc-Francard. Created by George Kay with François Uzan, the series is produced by Gaumont with Carrousel Studios.

Museums targeted, but never named

Netflix has not given the names of the robbed museums, nor the list of stolen items. The only indications come from the official photos of the season, signed by Emmanuel Guimier. One shows Assane, in a dark suit, red tie, and pinned badge, in the middle of a salon with gilded woodwork where crowns rest under glass display cases. Another places Belkacem and Guédira, with police armbands, in a long gallery of illuminated display cases.

The Parisian setting remains faithful to the series. One photo captures Assane disguised as a technician under the illuminated arches of the Eiffel Tower; another shows him on a metro platform with the Champs-Élysées sign, a small shining stone between two fingers. Filming took place in Paris: Netflix announced its start in May 2025, and Omar Sy announced its completion on 16 September 2025.

The Queen’s Necklace, a foundational jewel

It all began at the Louvre. In Part 1, Assane orchestrates a spectacular heist to steal Marie-Antoinette’s necklace, the jewel his father Babakar had been accused of stealing from the safe of his employer, Hubert Pellegrini.

The jewel has a very real history. According to historical accounts of the affair, Louis XV ordered a necklace in 1772 from jewellers Charles Auguste Böhmer and Paul Bassenge, intended for Madame du Barry. Completed in 1778, it brought together more than 600 diamonds for some 2,800 carats, and its creators offered it to Marie-Antoinette for 1,600,000 livres. The queen refused. The scam orchestrated by the Comtesse de La Motte at the expense of Cardinal de Rohan broke out on 15 August 1785; the necklace, already dismantled, had been sold stone by stone, partly in London.

Maurice Leblanc had seized upon it long before Netflix: his short story “Le Collier de la reine” (The Queen’s Necklace), published in the magazine Je sais tout on 15 April 1906, tells of the jewel’s theft by a still-child Arsène Lupin.

Black Pearl, bracelet, and stolen Manet

Part 3, released on 5 October 2023, shifted the plot towards high jewellery. Netflix summarises it thus: Assane steals the Black Pearl, an invaluable jewel linked to the Franco-Tahitian war, which he had already attempted to steal in 2017. This time, he warns the owners of the exact time of the theft, transmits his plan to the press, and a crowd comes to cheer him in front of the place where the pearl is kept.

Then come a gem-set bracelet and a painting, Édouard Manet’s Chez Tortoni. The latter is not an invention: the canvas is one of thirteen works stolen from the Isabella Stewart Gardner Museum in Boston on the night of 18 March 1990. The museum recalls that two men disguised as police officers had gained entry, and the case remains unsolved. The Black Pearl, too, comes from books: Leblanc published “La Perle noire” (The Black Pearl) in July 1906, with Lupin targeting a countess’s jewel.

When fiction catches up with the Louvre

Filming for Part 4 had been completed for a month when the Louvre experienced its own heist. On 19 October 2025, according to the museum, two criminals broke into the Galerie d’Apollon and stole eight 19th-century jewels. Among the pieces listed by the Ministry of Culture: the sapphire parure of Queens Marie-Amélie and Hortense, Marie-Louise’s emerald necklace, and Empress Eugénie’s diadem. Eugénie’s crown, abandoned during the escape, was found damaged.

The Paris prosecutor, Laure Beccuau, reported damages estimated at 88 million euros by the museum’s conservation. After several months of closure, the Galerie d’Apollon regained its function as a ceremonial gallery in summer 2026, according to the Louvre. The fourth part of Lupin is released four days after the first anniversary of the theft; nothing in the official synopsis refers to this incident.

From Étretat to La Santé, Leblanc’s legacy

The series has never hidden its source: Assane grew up with Maurice Leblanc’s novels. In the fifth episode of Part 1, he takes the train to Étretat with Claire and their son Raoul. Leblanc bought a house in Étretat in 1918, the Clos Lupin, where he wrote a large part of the saga; the house can be visited. It is also on this coast that he set L’Aiguille creuse (1909), whose rock hides the treasure of the kings of France: pearls, rubies, sapphires, and diamonds.

The starting point of Part 4 finally recalls the very first short stories. In “Arsène Lupin en prison” (1905), the burglar organises a theft from his cell in La Santé; in “L’Évasion d’Arsène Lupin” (1906), he announces his imminent escape to the police. A Lupin behind bars who must escape: Leblanc had established the motif one hundred and twenty years before Netflix. For the series’ locations to visit, from the Louvre to the Musée Nissim de Camondo, La Revue des Hôtels has listed the filming locations.

Eight episodes, one date

The eight episodes of Lupin Part 4 will be available on Friday 23 October 2026 on Netflix, all at once. Parts 1 to 3 remain viewable on the platform.
