‘Unforgotten’ season 6 release window, cast, plot, and more

One of ITV’s most beloved crime dramas is returning for a sixth season. Unforgotten, which sees a small yet effective team of London detectives unravel the intricacies of various tragic cold cases, has once again been renewed despite the fifth season’s major casting change. In 2023, Unforgotten season 5 was one of ITV’s most-watched programs, so this renewal isn’t necessarily surprising—but it’s certainly a welcome one.

Here’s everything we know about Unforgotten season 6.

When will Unforgotten season 6 be released?

Unforgotten season 6 has officially been released in the U.K. on ITV and ITVX as of February 2025, so the U.S. should not be far behind. Earlier this year, PBS Masterpiece confirmed that season 6 is officially part of their 2025 lineup, though an exact release date has yet to be confirmed.

The cast of Unforgotten season 6

Both Sinéad Keenan and Sanjeev Bhaskar will be reprising their roles as DCI Jess James and DI Sunil ‘Sunny’ Khan, respectively. The rest of the main cast includes Jordan Long as DS Murray Boulting, Carolina Main as DS Fran Lingley, Pippa Nixon as DC Karen Willets, Georgia Mackenzie as Dr Leanne Balcombe, Andrew Lancel as Steve James, and Kate Robbins as Kate.

Other cast members for this season include MyAnna Buring as Melinda Ricci, Victoria Hamilton as Juliet Cooper, Phaldut Sharma as Ram Sidhu, whom you may recognize from season 4, Maximilian Fairley as Marty Baines, Elham Elas as Asif Syed, Pixie Davis as Taylor Cooper, and more.

What will Unforgotten season 6 be about?

Unforgotten‘s fifth season had a lot to contend with—not only did it introduce a brand-new DCI to the team, but grief was a major theme, even more so than usual. Sunny, especially, was still grappling with the loss of his former partner, DCI Cassie Stuart (Nicola Walker), after she died in a tragic car accident in the season 4 finale.

DCI James, meanwhile, had to learn how to lead a grieving team while also dealing with her own personal drama, as her husband revealed he’d been having an affair in season 5’s premiere episode. Given all the emotional turmoil, it’s no wonder that Jess and Sunny butted heads when they first started working together, though thankfully, by the end, they’d fallen into a solid working pattern.

Unforgotten season 6 will build on the foundations of their partnership—one of the reasons Unforgotten is so beloved is that it doesn’t just care about the victims (both dead and alive) but its leading characters, too.

While previous seasons have unearthed forgotten crimes as far back as the ’70s, Unforgotten season 6 takes place closer to home. This season’s murder victim is Gerry Cooper, whose remains are found on Whitney Marsh after he vanished following a dodgy business venture. As it turns out, Gerry Cooper fell into debt during the COVID-19 pandemic (only four years ago!), and he had plenty more grisly secrets up his sleeve to boot.

You’ll have to watch the new season to find out who killed him.
