Former Shaolin man Marshal Kao takes his former classmates prisoner and, instead of executing them, proposes to his Qing commander that he torture them until theyre willing to fight on behalf of the Qings. The torture comes to look increasingly like strenuous kung fu training with Kao putting the prisoners through their paces. The Qing governor and his aides become suspicious of Kaos motives, although the beautiful Princess Shao Lung develops her own ideas about him.
