The Queen’s cousin was a playboy Royal who spent the 60s travelling the globe on diplomatic business. A love affair in Japan and a rare incurable blood disease caused scandal for the British Monarchy before his glamourous life was cut short when he crashed his plane in 1972. But why do we not know this other Prince William? This fascinating documentary, packed with evocative archive footage, documents the romance between Prince William of Gloucester and glamorous divorcee, model and former air hostess Zsuzsi Starkloff.
