Legends: Netflix’s True-Crime Drama About Undercover Customs Officers Returns For Season 2

Netflix viewers who have already raced through Legends have more to look forward to. The six-part British crime drama, inspired by the previously untold true story of Customs officers who infiltrated some of the country’s most dangerous drug gangs in the 1990s, has officially been renewed for a second season.

Created by Neil Forsyth, the series premiered on Netflix in May 2026 and follows a group of ordinary civil servants who are given new identities and sent undercover into the criminal underworld. All six episodes are currently available to stream.

An Unusual Undercover Operation

The story begins in the early 1990s, when Her Majesty’s Customs and Excise was struggling to stop illegal drugs entering Britain.

Instead of relying on highly trained spies, the operation recruited ordinary Customs employees from across the country. They were given basic training and tasked with creating entirely new identities — their “legends” — before attempting to infiltrate criminal networks from the inside.

That setup puts the characters in an especially dangerous position. They must convince experienced criminals that their new identities are genuine while trying to protect their real lives and families outside the operation.

The Netflix series follows several undercover threads, including Guy’s increasingly risky position within the criminal world and the team operating in Liverpool. As the investigation develops, alliances become unstable, surveillance operations go wrong and maintaining a cover becomes increasingly difficult.

A Crime Drama Driven By Its Characters

One of the strengths highlighted by viewers is the attention given to the individual members of the undercover team.

Each character has their own reasons for becoming involved in the fight against Britain’s drug problem, giving the operation a personal dimension beyond the wider investigation.

The ensemble includes Tom Burke as Guy, Steve Coogan as Don, Hayley Squires as Kate, Tom Hughes as Carter, Aml Ameen as Bailey and Jasmine Blackborow as Erin.

The cast also features Douglas Hodge, Johnny Harris, Gerald Kyd, Numan Acar, Charlotte Ritchie, Joshua Samuels, Kem Hassan and Thomas Coombes.

Viewers Praise Its Authentic Feel

Audience reactions have particularly focused on the series’ pacing, atmosphere and performances.

One Rotten Tomatoes viewer described the drama as feeling different from more familiar British crime series, praising the way the story moves quickly while still giving audiences the information they need to understand the investigation.

Another viewer highlighted the characters, period atmosphere and attention to detail, including the music, clothing and overall look of the late 1980s and early 1990s.

The performances have also drawn attention, with one audience member singling out Gerald Kyd for his portrayal of Mylonas and describing the series as highly watchable and easy to binge.

Those reactions reflect what the show is designed to deliver: a crime thriller built around the risks of undercover work rather than simply following a conventional police investigation.

Six Episodes, One Increasingly Dangerous Operation

Across its six episodes, Legends gradually raises the stakes for the undercover team.

The opening episode introduces the recruitment of a new Customs unit as drug deaths rise across 1990s Britain. Guy then faces threats to his cover, while the Liverpool operation begins pursuing its own leads.

Later episodes push the team deeper into the criminal world. Guy becomes involved in a high-risk smuggling deal, tensions begin to fracture the criminal groups they are investigating, and Kate searches for weaknesses in Carter’s cover.

By the fifth episode, Guy, Bailey and Don are facing a dangerous mission overseas while Kate follows a potentially corrupt trail. The finale brings betrayal, suspicion and ambition together as the undercover identities — and the wider operation — come under serious threat.

Season 2 Is Officially Happening

Netflix confirmed the renewal of Legends in August 2026, with Tom Burke and Steve Coogan returning alongside the undercover team.

The second season will continue the story of the unlikely group of Customs employees as they are drawn back into undercover work. Netflix says the characters had returned to their ordinary lives after the events of the first season, but they will soon find themselves back in the criminal world while the outside world remains unaware of what they are doing.

Neil Forsyth will return to continue telling the story, with production scheduled to begin in 2027. Netflix has not yet announced an official premiere date for Season 2.

All Six Episodes Are Streaming Now

For anyone looking for a British crime thriller rooted in a real investigation, Legends offers a story built around undercover identities, criminal networks and the constant danger of being exposed.

The first season consists of six episodes, all currently streaming exclusively on Netflix.

And with Season 2 now confirmed, the undercover operation is far from over.
