The Maya were an advanced and powerful people who dominated Central America for over 700 years.

Follow in the footsteps of renowned Maya expert Dr. Nikolai Gruber as he travels deep into the Guatemalan jungle in an attempt to solve the puzzle of just who, or what, brought about the demise of this once glittering civilization.
