Nottingham, 1984. Private detectives Matt Crawford and Kate Brooks are hired by a jeweller to find their estranged father, an ex-army Major, who served in the Far East after WW2. All they have is a list of family and friends and an old leather trunk full of military memorabilia. When they discover the Major’s disappearance is connected to an unsolved murder from 1950, events take a new twist. They are threatened by a notorious gang and suspect their missing man is the key to finding the killer. There is no such thing as coincidence. Everything happens for a reason.
