For roughly 3,000 years the Maya built temple cities across Central America before their kingdoms emptied out, and this film follows archaeologists trying to explain why. Fresh excavations and scanning technology reveal royal tombs packed with jade and painted ceramics, evidence of the lavish lives their kings led at the height of the civilization's power. The film also examines the darker side of Maya religion, including the ritual sacrifice performed to keep their gods satisfied, and what it suggests about the pressures building inside these societies. Researchers on site walk through pyramid complexes and newly opened burial chambers, connecting architecture and inscriptions to the droughts, warfare, and political strain that theories point to as causes of the collapse. Rather than settling on one explanation, the film lays out the competing evidence for climate failure, internal conflict, and overextended kingdoms, treating the disappearance of Maya cities as an unresolved puzzle that new digs keep reshaping.
