Here's some good news for Unforgotten fans in the US: The British crime series is finally returning to US screens with its sixth season. The new season already aired in the UK earlier this year, and now American viewers have a confirmed release date.

Known for its storytelling and slow-burn cases, Unforgotten has gained a strong fan base since it first aired in 2015. The series focuses on cold cases and murders from the past that are reopened when new evidence comes to light. Every season tells a new story with a new case, while continuing the personal journeys of the detectives.

According to TV Line, after airing in the UK on ITV in early 2025, Season 6 of Unforgotten is coming to the US on PBS Masterpiece on August 24, 2025. It will also be available for streaming on PBS Passport.


Everything we know about Unforgotten season 6

Unforgotten follows two detectives as they investigate unsolved murder cases. The show began with DCI Cassie Stuart (played by Nicola Walker) and DI Sunny Khan (played by Sanjeev Bhaskar). Together, they reopened cases when new evidence was found. After Cassie’s tragic death in Season 4, the team welcomed a new leader, DCI Jessie James (played by Sinéad Keenan), in Season 5.

Each case or season reveals how people’s lives can be altered or ruined by past crimes. The suspects are often ordinary people who are hiding painful secrets. The series carefully shows how guilt, shame, and silence affect families, friendships, and communities.

In season 5 of the UK crime series, DCI Jessie James took over as the new team leader. She had a rough start, clashing with Sunny and struggling with problems in her personal life. Despite the tension, they worked together on a case involving a severed leg found in a chimney. The case led them to a group of friends connected by a dark incident from their university days.

The fifth season of Unforgotten ends with the killer being revealed, and Jessie finally begins to earn the trust of her team. Sunny also started to understand Jessie better, making it easier for them to work together in future cases.

In Unforgotten Season 6, a woman’s body is found buried in the garden of a house in South London. The body is linked to a missing person's case from 2004. Sunny and Jessie work through old records, interview former suspects, and uncover long-hidden lies. The investigation affects both of them deeply, especially Jessie, whose own past becomes more important this season.

For season 6, Sanjeev Bhaskar returns as DI Sunny Khan. Sinéad Keenan continues as DCI Jessie James. Supporting cast includes Jordan Long as DS Murray Boulting and Carolina Main as DC Fran Lingley. Chris Lang and Andy Wilson return as creator and director, respectively.
