Did Richard III kill his nephews? Philippa Langley and Rob Rinder explore new discoveries and examine the truth about the fate of the princes in the tower. Based on The Missing Princes Project.

This documentary looks at the search for the remains of King Richard III of England (1452-1485). After being killed in the Battle of Bosworth Field (August 22, 1485), his remains were taken to Leicester and it was believed that he was buried at Greyfriars Church. The church no longer exists and its remains were now believed to be under a car park. Phillipa Langley of the Richard III Society convinced archaeologists at the University of Leicester to lead a dig and surprisingly, as it turned out, the first skeleton they found was subsequently proven to be that of the King through DNA tests which showed a match to Canadian Michael Ibsen, a direct descendant of Richard III's sister.

In this special follow-up programme, the only television team with access to the dig and the scientific tests on the skeleton uses unseen footage and conducts two days of additional interviews to tell this extraordinary forensic detective story in even greater scientific and archaeological detail.

An amateur historian defies the academic establishment in her efforts to find King Richard III's remains, which were lost for over 500 years.
