In 1910, Dr. Hawley Harvey Crippen was hanged for poisoning and dismembering his wife, after having tried to flee the country with his young lover. However, investigators have now found that the human remains discovered in Crippen's cellar were not those of his wife at all. Their further DNA work - revealed exclusively in this film - throws up startling new evidence about what really happened. It exposes a historic miscarriage of justice and poses uncomfortable questions about the police and prosecutors of the time, who claimed to have solved the crime of the century.
