From the makers of acclaimed, hard-hitting documentaries How to Die: Simon’s Choice, Abused: The Untold Story and The Detectives comes this new one-off film about the 1996 murders of Lin Russell and her six-year-old daughter Megan, and the attempted murder of nine-year-old Josie, in the Kent village of Chillenden.

Independent experts look back at the crime and examine the case of local man Michael Stone, who was charged, found guilty and sentenced to life in prison but has long maintained his innocence.

Is the right person in prison for the crime that appalled the nation over two decades ago?
