The Great Wall of Chine runs 5500 miles in length and took 1700 years to build. It has kept out many enemies of China, both known and that of legend. This is a tale of a legend. Two European mercenaries, William and Tovar (Matt Damon & Pedro Pascal) come to China in search of black powder. They find themselves at the Great Wall as the army there prepares for battle against a mystical enemy, the Tao Tei, a cross between a dragon and a dog. The two men just want to get what they came for and reap the benefits for bringing it home, but William starts to feel he may be involved in a fight worth more than any financial reward.
