The past cannot stay buried forever, and this critically-acclaimed Masterpiece drama begs the question: what does it take to fight for justice while preserving one's own sanity? Written by creator and executive producer Chris Lang, the fourth season of Unforgotten cracks open the series’ most compelling mystery yet.
Nicola Walker (Last Tango in Halifax, Babylon) and Sanjeev Bhaskar (Yesterday) return as DCI Cassie Stuart and DI Sunny Khan, veteran partners in solving the tangled, complicated murders of the past. As the duo investigates a cold case with chilling ties to the local police force, loyalties are tested and emotions wear thin. Who can they trust when suspects are everywhere? And will Cassie and Sunny find themselves on the wrong side of the law?
