Secrets of the Dead: Season 15, Episode 5

15 - 5: Teotihuacan's Lost Kings

Following a team of international scientists, this film exclusively documents an archeological sensation: the exploration of royal tombs beneath the ancient Mexican city of Teotihuacán. Despite many decades of research, not much is known about the long-lost Teotihuacán society. But when archeologists enter the newly discovered burial chambers, they find the clues that may finally tell us who these mysterious people were.

The film incorrectly states the city of Tikal is in Mexico when it is in Guatemala. Secrets of the Dead strives to get the facts correct and regrets the error.
