Sam and Trey are tasked with saving the world from total destruction by gathering the scattered fragments of the Warrior's Shield. Their next stop is ancient China, where they need to track down the third piece - fast! Transported to a misty bamboo forest, they are attached by the shape-shifting Monkey King. They manage to strike a deal to save their lives: if they can recover a stolen treasure from the malicious Lord Liu, then maybe, just maybe, he will help them. But Liu is a Lord of the Dark, part of the evil that Sam and Trey are fighting. Can they trust the mischievous monkey to help them defeat him? There's only one way to find out.
