Netflix’s New Crime Thriller Legends Makes a Strong Early Impression With Audiences
Netflix’s six-part crime thriller Legends has made an immediate impression with viewers, earning an 84% audience score on Rotten Tomatoes from more than 250 ratings as of September 17, 2026. The series currently holds an even higher 97% Tomatometer score from 34 critics.
Created by Neil Forsyth, Legends dramatizes the little-known story of British Customs officers who went undercover to infiltrate major drug-trafficking networks during the early 1990s. The six-episode series premiered on Netflix on May 7, 2026, and stars Tom Burke, Steve Coogan, Hayley Squires, Tom Hughes and Aml Ameen.
A Crime Thriller Based on a Remarkable True Story
The series is set during a period when Britain was struggling to contain the flow of illegal drugs across its borders. Rather than relying on trained intelligence agents, the operation recruited ordinary Customs employees and placed them inside criminal organizations under carefully constructed false identities.
Those identities became their “legends,” allowing the officers to operate undercover while attempting to gain the trust of people involved in the drug trade. Netflix describes the story as being inspired by an untold true story, while reporting from The Independent connects the drama to a secret Customs operation involving undercover officers in the early 1990s.
That unusual premise gives Legends a different angle on the familiar crime-thriller formula. The characters are government employees who suddenly find themselves having to improvise their way through an increasingly dangerous criminal world.
The six episodes follow the undercover mission as the officers attempt to penetrate drug gangs, maintain their cover and gather enough information to disrupt the networks they have entered. Netflix’s episode descriptions show the operation becoming progressively more dangerous, with undercover identities threatened, volatile alliances forming and a major heroin shipment putting the entire mission at risk.
Steve Coogan Leads a Strong Ensemble
Steve Coogan headlines the cast alongside Tom Burke and Hayley Squires. The wider ensemble includes Jasmine Blackborow, Douglas Hodge, Charlotte Ritchie, Tom Hughes, Johnny Harris, Gerald Kyd, Numan Acar, Joshua Samuels, Kem Hassan, Thomas Coombes, Alex Jennings, Con O’Neill, Deepak Verma and Cecily Cleeve.
Burke plays Guy, one of the Customs recruits sent undercover, while Coogan plays Don and Squires portrays Kate. Tom Hughes appears as Carter, with Aml Ameen playing Bailey.
The central performances are an important part of the show’s appeal. The undercover premise depends on characters who can convincingly move between their ordinary professional lives and the criminal identities they have created, giving the ensemble plenty of room to explore the pressure and uncertainty involved.
Viewers Have Responded Strongly
The early audience response has been particularly positive. Rotten Tomatoes currently lists Legends at 84% from more than 250 audience ratings, although that figure can change as additional viewers submit reviews.
Critics have been even more enthusiastic, with the series sitting at 97% on the Tomatometer from 34 reviews. Individual reviews have praised its brisk storytelling, suspense and ability to balance the seriousness of its subject with moments of humor.
The response also reflects the appeal of the real-life story behind the drama. The fact that the characters are based on ordinary Customs employees undertaking an extraordinary undercover operation gives the series a grounded quality, while the criminal investigation provides the tension expected from a modern crime thriller.
A Six-Episode Story With Plenty of Momentum
Despite being limited to six episodes, Legends covers a broad criminal investigation.
The opening episode introduces the undercover mission as drug deaths rise in 1990s Britain and the government turns to a veteran Customs investigator to assemble an inexperienced unit for an unprecedented operation. In the second episode, Guy faces challenges that could expose his identity while the Liverpool team investigates a suspicious bakery.
The danger increases in the third episode, when Guy becomes involved in a high-risk smuggling deal and the Liverpool operation takes a dangerous turn. By the fourth episode, pressure and paranoia are beginning to fracture the criminal organizations, while Kate looks for a potential weakness in Carter.
The final two episodes raise the stakes further. Kate follows a possible corruption trail, while Guy, Bailey and Don undertake a dangerous overseas mission connected to a potential meeting with a feared drug lord. The finale centers on betrayal, distrust and ambition as the undercover operation faces the threat of an unprecedented heroin shipment reaching Britain.
The Real Story Behind Legends
The show’s real-world foundation is one of its most intriguing elements.
According to reporting on the history behind the series, the undercover Customs program was known as the Beta Projects and began around the late 1980s and early 1990s. Officers were given false identities and had to rely heavily on ingenuity while operating with limited resources.
The Times reports that Legends was inspired by the memoir The Betrayer, written under the pseudonym Guy Stanton by a former undercover Customs officer. The newspaper also notes that some characters are composites and that the series takes certain dramatic liberties while drawing heavily on the experiences of the real undercover officers.
That distinction is worth keeping in mind when watching the series. Legends is a dramatization rather than a documentary, but its central premise is rooted in a real undercover operation.
A Strong Addition to Netflix’s Crime Lineup
Netflix already has an extensive selection of crime dramas and thrillers, but Legends arrives with a premise that gives the genre a fresh perspective. Its six-episode structure keeps the story focused, while the undercover setting provides plenty of opportunities for tension as the characters attempt to maintain identities that could collapse at any moment.
With strong reviews from critics, an 84% audience score and a story drawn from a little-known chapter of British criminal investigations, Legends has quickly established itself as one of Netflix’s notable crime dramas of 2026.
For viewers interested in crime stories based on real events, undercover investigations and tightly paced limited series, the show offers a six-episode narrative built around an unusually dangerous assignment.
