The Lost Treasure of the Grand Canyon

In the early days of the 20th Century, an expedition led by Dr. Samuel Jordon traveled deep into the Grand Canyon in search of a long-rumored hidden city. The entire team disappeared. But when Jordon's archaeologist daughter Susan (Shannen Doherty) leads a rescue party into the uncharted valley, she will discover an ancient civilization ruled by savage warriors, human sacrifice and a mythological monster that feeds on carnage. Even if the explorers can survive the deadly trials of the Aztecs, will they find a way to escape the ultimate ritual of evil? (official distributor synopsis)
