    What is Unforgotten Season 5 About?

    Actor Sinéad Keenan as DCI Jessica James in Unforgotten on MASTERPIECE on PBS.

    Viewers heartbroken after the Season 4 finale will be reassured by a returning show that The Guardian (UK) says is “as taut and tense and pleasurable as ever.” As Season 4 wrapped up, we saw DCI Cassie Stuart involved in a violent car crash. Family and friends gathered at the hospital, and DI Sunny Khan was moved to propose to girlfriend Sal. In the end, Cassie didn’t make it. Sunny eulogized his close friend and mentor and plunged into deep grief.

    As Season 5 begins, our investigative police unit, especially Sunny, is still mourning the loss of DCI Stuart. Enter the business-like and abrupt new boss, DCI Jessica James, to investigate the discovery of human remains in a newly renovated home in West London. She needs to be at the top of her game, but her first day on the job is marred by a crushing surprise in her family life. How will a grieving team and a fractious boss ever find their rhythm?
