The Real Temple of Doom

S2 E1: Thousands of years before the Inca ruled the nation now called Peru, a strange and unique civilization dominated the region. It was called Chavín, and its story is one of the most bizarre in world history. Unlike the other civilizations of the Americas, Chavín status as a regional superpower wasn't based on its military muscle. Instead, Chavín rulers exercised a cult-like control over their subjects with the aid of hallucinogenic plants.  Josh Bernstein ventures deep into the miles of tunnels that lay beneath the ruins of Chavín de Huántar; comes face to face with some of the most fearsome animals of the Peruvian Amazon; and investigates a real temple of doom.  As he tries to understand this mysterious culture, he takes part in one of the ancient rituals still practiced by the country's powerful shaman-priests.
