Sentinels of Silence provides an 18-minute helicopter-based aerial visit across the archeological sites of Mayan ruins across Mexico and Central America, including Teotihuacan, Monte Alban, Mitla, Tulum, Palenque, Chichen Itza and Uxmal. The film's narration details pre-Columbian Mayan culture, focusing on its achievements in mathematics and astronomy, and then questions how and why the Mayan society seemed to disappear, leaving behind its structures as the eponymous silent sentinels.
