Critically acclaimed ITV drama series Unforgotten starring Nicola Walker and Sanjeev Bhaskar returns for a second series. The story begins with the discovery of a body; this time the perfectly preserved remains of a middle aged man found in a sealed suitcase in the silt of the River Lea in northeast London. As Cassie and Sunny begin the complicated task of trying to identify the victim, we will meet four unconnected people who we suspect are linked in some way to the victim.
