Set in the early Republican era, when bandits ran rampant across the western deserts, this film unfolds as a legendary biopic of an extraordinary figure. The "Wolf King," after provoking a powerful crime syndicate in the heartland, is forced to flee to the remote northwest. There, he unexpectedly crosses paths with "Jade Lotus," the most sought-after courtesan of the Joyful Tower. However, when Jade Lotus sacrifices herself to save him, she is mortally wounded. With her dying breath, she implores the Wolf King to avenge her family by eliminating the ruthless bandit leader known as the "Ghost King"—the scourge of the west.
