Orphaned young, Ming Tsu, the son of Chinese immigrants, is raised by the notorious leader of a California crime syndicate, who trains him to be his deadly enforcer. But when Ming falls in love with Ada, the daughter of a powerful railroad magnate, and the two elope, he seizes the opportunity to escape to a different life. Soon after, the tycoon’s henchmen kidnap Ada and conscript Ming into service for the Central Pacific Railroad. A heartbroken yet defiant Ming partners with a blind clairvoyant known only as the prophet. Together the two set out to rescue his wife and to exact revenge on the men who destroyed Ming, aided by a troupe of magic-show performers --- some with supernatural powers --- whom they meet on the journey.
