In the Ming Dynasty, “Chin Yi Wei”—the Imperial Guards directly report to the Emperor. However, as the eunuch is in power, Chin Yi Wei become the eunuch’s tools to eliminate the rivals. When Japan presents tribute to the Ming Emperor, all the tribute, including a beauty, is held up by Eunuch Ma Tang. Through an extremely keen competition, Ma Tang chooses two warriors of matchless martial arts. One of the two is named Ti Yung who under Ma Tang tries by all means to destroy the opposition power against Ma Tang. At the time, a strong foe named Wen Yang pretends to be loyal to Ma Tang and becomes a member of Chin Yi Wei. In the eve of Ma Tang’s birthday, he launches an operation to assassinate Ma Tang. At the most crucial moment, it is Ti Yung who protects Ma Tang from being killed. Now, Ti Yung wins full favor from Ma Tang and is promoted rapidly and finally becomes his No. 1 man. The Japanese beauty by her spell-bound charm seduces Ma Tang and in secret learns his Kungfu, and then teaches the Kungfu so learned to Ti Yung. In a troop inspection, Chin Yi Wei has a big rebellion and after the earth-shaking combats, Ma Tang is finally killed by Ti Yung. When all the public are so happy to see the end of a big traitor, the public, having so strong resentment against Ti Yung, kill Ti Yung after all. At the moment the imperial decree arrives and everything is known clearly. Ti Yung was a true member of the Imperial Guards. He just pretended to be loyal to Ma Tang but his eventual goal was to kill the traitor eunuch Ma Tang. Before he finally attained his mission, he was willing to be misunderstood by all. This is just the true courage.
