Jago begins by journeying through southern Mexico to investigate the rise and fall of America's oldest civilisation, the Olmec, which thrived over 3,000 years ago. He encounters colossal stone heads and the oldest rubber balls in the world and descends deep inside an ancient cave network in search of a were-jaguar.

Jago explores the forgotten people of ancient Costa Rica, who built a series of spectacular settlements amongst the rivers and volcanoes of central America and whose enigmatic legacy - including hundreds of mysterious, giant stone spheres - is only now being unravelled by archaeologists.

The Taino people of the Caribbean were the first people of the Americas to greet Christopher Columbus. But, as Dr Jago Cooper reveals, they had a multicultural society complete with drug-infused rituals, strange skulls and amazing navigation. In deep caverns and turquoise seas, Jago uncovers their hidden history.

Jago explores the ancient civilisation of Teotihuacan that exploded into a position of dominance in the ancient Americas almost 2,000 years ago. For hundreds of years this great city state was the biggest in the New World. Its rulers built monumental pyramids and temples and then went on to build a vast empire that was maintained through force. Yet the identity of the people who led this civilisation remains a mystery.
