This episode puts Menzies' controversial theory to the test, visiting locations to search for clues and drawing together contemporary historical accounts, archaeology and a wealth of evidence from consultations with scholars to investigate Menzies' claims. Historians, archaeologists and scientists cast major doubts on the claims that the Chinese rounded the Cape of Good Hope, that they entered the Atlantic Ocean, that they visited or settled in America or indeed produced a Master Chart of the World. Menzies claims he can' t be proved wrong. However, the discovery that led to his investigation has unearthed mysteries surrounding both the discovery of America and the true nature of the Ming voyages.
