Lastly, we have another British crime drama. However, "Unforgotten" focuses on a section of the police department that looks specifically at old unsolved cases, with the aim to solve and close the cases. Following the investigations of DCI Cassie Stuart and DS Sunil Khan, the show uncovers the effects of cold cases on the detectives as well as the victim’s families and friends. The show is currently on its third season and each season deals with a different case of murder or disappearance.
