The demons that could control stones and elementals have been defeated, but the most powerful of Simon Wong's associates still remains to create almost undetectable copies of humans and Shen. This demon allies with Kitty Kwok to prepare a torturous trap for Emma and Simone, from which they may never return.

Wudang Mountain is enveloped by dark foreboding as Xuan Wu begins to reappear - sometimes human, sometimes turtle, but always without memory.

Emma and Simone are in a race against time as they try to rescue Xuan Wu ... before the demons capture him.
