) and DI Sunny Khan (Sanjeev Bhaskar, The Indian Doctor
) are called in for another seemingly impossible cold case. When human remains are found by a London highway, a close-knit group of old school friends hold the key to what happened. But none of them are quite who they seem to be. Is one of them capable of murder? "Beautifully crafted and performed…there is no better drama on television."— The Guardian
