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?
