A callous orphanage attack...

A gigantic conspiracy, crossing junctures and factions...

And four fatherless men, each related to the others by blood.

Air, Earth, Fire, Wood, Water - the cornerstones of an abominable plot to control the world's chi. To stop it our heroes must wage a kung fu campaign across time, from modern-day Hong Kong to 1850s Canada to 2056 Containment Site DS4S. The missiles-flying, choppers-exploding, bullet-ridden climax brings them to Three Gorges Dam, a colossal structure that will divert the flow of the hallowed Yiangtze River.
