About the Show

Nicola Walker (Last Tango in Halifax, Babylon) and Sanjeev Bhaskar (Yesterday) star as DCI Cassie Stuart and Cassie’s partner-in-solving-crime, DI Sunny Khan, who are veterans at uncovering the truth of tangled, complicated murders of the past. But the deeper the truth lies, the bigger the emotional toll for the suspects, the families left behind, and for Cassie and Sunny to handle. How long can one fight for justice while preserving their own sanity?

In Unforgotten Season 4, the British Academy Film Awards (BAFTA) award-winning series’ most dramatic season yet, Cassie and Sunny investigate a cold case with alarming links to the police force when a corpse is discovered in a scrap yard, his features frozen in time. All four suspects have links to the law and attended the same police training course back in 1989. But who exactly is fighting for justice? Can the police force ever really be trusted? And will Cassie and Sunny find themselves on the wrong side of the law? Guest stars in Season 4 include Alastair Mackenzie (Wolf Hall), Liz White (Life on Mars), Daniel Flynn (Father Brown), and more.
