In 18th-century China, during the Manchu-led Qing dynasty, the Red Flower Society, a Han Chinese organization led by Chan Gar-lok, battles against Emperor Qian Lung to return the country to the Han Chinese.

The rebellious Red Flower Society, led by their chief Chan Gar-lok, attempts to assassinate the Ching Emperor Qian Lung. But a shocking discovery leads to a fierce showdown and Chan's exile to the Western frontier, where he meets the legendary Princess Fragrance. Together with the nomads, Chan executes a daring return to the capital and an audacious plan to capture Qian Lung.—Tai Seng
