While defending his country against Japanese invasion, archaeologist Chuan-Jay Hoo is taken as a prisoner of war when a behind-enemy-lines rescue mission goes horribly wrong. His captors force him to take part in the excavation of an ancient tomb, a process that unearths a ruthless force and the true origin of Chinese civilization.

The excavation ends; but China is still in dire need of help. Teamed up with American adventurer Dr. Harry Jones, a close friend of President Roosevelt, Chuan-Jay returns to the tomb and convinces the guardians of the tomb to interfere human affairs.

The tide of the war is turned but no one sees what is coming next: the rise of an otherworldly evil. Neither the Allies nor the Axis powers can stand in its way. Soon, our world is at the brink of an Armageddon.

At the final moment of human civilization, Chuan-Jay finds himself standing alone in the tomb of the First King, as the last line of defense for the survival of mankind.
