In the midst of Beijing's urban bustle, ambitious young 'Tiger' Chen Lin-Hu (Tiger Hu Chen) works as a lowly courier; but after work, he is a young martial arts star, rising through the ranks representing the Ling Kong Tai Chi tradition. He has crafted the stealthy, peaceful movements of Tai Chi and sculpted them to suit martial arts' competitive fighting world. Jumping to another central city of pandemonium and chaos, Donaka Mark (Keanu Reeves) is evading the police in Hong Kong while running an underground fight club where cold hard cash is made by defeating one's opponent in a no-hold's barred fight privately broadcast to wealthy patrons. Looking for a new 'star', Donaka tries to lure Tiger with the promise of easy money. Entrance into this world brings out the darkest side of Chen Lin-Hu, but he needs the cash.
