National Geographic Explorer Albert Lin travels to the jungles of Central America in search of the lost capital of the Maya Snake Kings.

During the Second World War, thousands of men and women from the Caribbean colonies volunteered to come to Britain to join the fight against Hitler. They risked their lives for king and empire, but their contribution has largely been forgotten. Some of the last surviving Caribbean veterans tell their extraordinary wartime stories - from torpedo attacks by German U-boats and the RAF's blanket-bombing of Germany to the culture shock of Britain's freezing winters and war-torn landscapes. This brave sacrifice confronted the pioneers from the Caribbean with a lifelong challenge - to be treated as equals by the British government and the British people. With vivid first-hand testimony, observational documentary and rare archive footage, the programme gives a unique perspective on the Second World War and the history of 20th-century Britain.
