In the early days of the 20th century, an expedition led by Dr. Samuel Jordon (Duncan Fraser of THE EXORCISM OF EMILY ROSE) 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 of TV's CHARMED, TV's BEVERLY HILLS 90210) leads a rescue party into the uncharted valley, she discovers 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?
