One of mankind's greatest wonders. 1700 years to build. 5500 miles long. What were they trying to keep out?
In ancient China, a group of European mercenaries encounters a secret army that maintains and defends the Great Wall of China against a horde of monstrous creatures.
When a mercenary warrior (Matt Damon) is imprisoned within the Great Wall, he discovers the mystery behind one of the greatest wonders of the world. As wave after wave of marauding beasts besiege the massive structure, his quest for fortune turns into a journey toward heroism as he joins a huge army of elite warriors to confront the unimaginable and seemingly unstoppable force.
Two days ride north of the Great Wall, sometime during the Song Dynasty, William Garin and Pero Tovar--survivors of a small mercenary group searching for gunpowder--narrowly escape an attack by a team of nomadic bandits. Without delay, the two friends seek refuge inside a seemingly safe cave; however, the following day will find them in shackles, standing before Commander Lin Mei and Strategist Wang who prepare for an all-out monster invasion within the following hours. Sooner or later, William and Pero will get caught in the middle of a war against a surprisingly intelligent Beast-Queen and her invincible army--a final confrontation for freedom and the fate of the entire human race. Can Commander Lin Mei and William stop the assault before it's too late?
