The return of the dedicated Cold Case investigators in this gripping, contemporary drama. They are faced with the challenge of four unsolved crimes which have lain dormant for years: the suspicious death of a war photographer in a car accident; a skull buried for 20 years in a church crypt which shakes the local Catholic community to its core; a double murder to which a woman confessed and served 25 years in prison, and a policewoman - was she the victim of a stalker, her estranged husband or the father of her unborn daughter?
