6 - 4: Shallow Grave

Police are digging in the back garden of a house in Luton searching for the body of a woman who disappeared in 2003. They believe a painstaking fingertip search might reveal vital clues in a suspected murder enquiry. Natalia Wilkanowska's disappearance left detectives from the Major Crime Unit puzzled and frustrated with the lack of answers to their questions. Without answers the family can't lay her memory to rest and properly grieve. Cameras follow every extraordinary twist and turn of an investigation where detectives have decided it's time to solve the job by turning up the heat on their suspects. This is real-life crime drama at its most intense.
