Mingchao, Chinese youth and orphan, travels through the "Old West" with the hope of gaining glory and fame. She rapidly joins up with a suspicious priest, Baskerville, and together they head for Hollywood.
Throughout their journey, they are harassed by tricksters and bandits. Mingchao's only memory of her late grandfather, one "Eto gun," appears to be on the minds of the troublemakers and supposedly gives significant power to the one that controls it.
