Lupin Part 4 Trailer Sends Assane After a Copycat — All Eight Episodes Arrive October 23

Netflix has released the official trailer for Lupin Part 4, revealing the problem waiting for Assane Diop after four years in prison: someone else has started playing his game. Omar Sy returns as Assane, trying to rebuild his life with his family when a mysterious copycat forces him back into action. All eight episodes arrive October 23.

Where Part 3 left off

Spoilers for Part 3 follow. Assane didn’t get caught at the end of Part 3 — he chose to turn himself in. After securing his family’s safety and Benjamin’s release, he voluntarily surrendered to the police, closing out the season on his own terms rather than being cornered. That distinction matters for understanding where Part 4 picks up: this isn’t a story about Assane failing to escape justice. It’s about what happens after he accepted it.

Four years later, and a copycat problem

Netflix’s own synopsis picks up roughly four years after that surrender: Assane has served his sentence and is finally ready to start a new life with his family. That plan doesn’t survive contact with the new season’s premise for long. A mysterious figure begins committing a wave of simultaneous museum heists signed with Lupin’s name — and, per early coverage of the trailer, evidence appears to place Assane himself at the scene of one robbery that leaves a police captain seriously injured. Someone is either impersonating him or setting him up, and either way, Assane can’t stay out of it.

It’s worth being precise about one thing the trailer doesn’t spell out: the exact mechanics of how Assane’s prison chapter ends. Netflix’s official framing is that he’s served his time and is ready to move on — not that he escapes or is released early under other circumstances. Treat “he served his sentence” as the confirmed version, not any more dramatic alternative some trailer-reaction coverage has speculated about.

What the trailer shows vs. what’s confirmed

The footage leans into Assane’s usual toolkit — disguises, misdirection, high-society infiltration — set against the new mystery of who’s operating under his name. What it doesn’t confirm: the copycat’s identity, their motive, or whether they’re working alone. Don’t trust any theory about who’s behind the mask until Netflix or the show itself actually reveals it; the trailer is deliberately built to keep that hidden.

Returning cast

Omar Sy returns as Assane Diop, alongside Ludivine Sagnier as Claire, Antoine Gouy as Benjamin Ferel, Soufiane Guerrab as Youssef Guédira, and Shirine Boutella as Sofia Belkacem. Théo Christine and Laïka Blanc-Francard join the cast as newcomers to the series.

October 23, eight episodes, all at once

Lupin Part 4 releases all eight episodes simultaneously on October 23, 2026 — Netflix has not described any weekly rollout for this season, so there’s no staggered release to plan around. George Kay created the series in collaboration with François Uzan, with Edouard Salier, Everardo Gout and Hugo Gélin directing Part 4’s episodes.

What Netflix still hasn’t revealed

The copycat’s identity remains the season’s central mystery, and Netflix’s marketing has kept it that way deliberately — no name, face, or motive has been confirmed. Beyond the broad four-years-later setup and the museum heist wave, plot specifics for individual episodes haven’t been detailed either. Treat anything more specific as speculation until the season itself airs.
