The search for an ancient treasure turns deadly when a group of fortune-hunting adventurers fall victim to a powerful Aztec curse. At the dawn of the 20th Century, Dr. Samuel Jordan led a team of explorers deep into the Grand Canyon in search of a mythical lost city. They were never heard from again. Convinced that her father is still alive, Dr. Jordan's archeologist daughter Susan (Shannon Doherty) assembles a rescue party and guides them into the uncharted valley. There, Susan and her team come into contact with an ancient civilization that practices human sacrifice in order to appease a mythical monster that thrives on carnage. With savage warriors closing in on all sides and an unimaginable evil hot on their heels, the terrified explorers struggle to escape before they become the guests of honor at a horrifying ancient ritual. ~ Jason Buchanan, All Movie Guide
