The disappearance, in sinister circumstances, of the boy king Edward V and his younger brother Richard has been the cause of speculation and fascination for over five centuries. They were presumed to have been murdered by their treacherous uncle who, as Richard III, seized power after imprisoning them in the Tower of London.

But eight years later a young man appeared and told an astonished world that he was Richard, the younger of the two princes. He had survived the attempt on his life and had come to claim his rightful place on the throne of England..

Before his final arrest, he won enough support in Europe to attempt to invade England three times and shake England's fledgling Tudor dynasty to its roots.

Was he genuine? Was this charismatic young man a prince of York? And could he reveal what really happened in the Tower all those years ago? Or was he Perkin Warbeck, a brilliant imposter, trained to carry out one of the most audacious cons imaginable?

This gripping drama is an imagined account of the final interrogation of a man who sought to change the course of British history and whose identity has remained a mystery to this day.
