Et Cetera

Mingchao lives in the good-old American West with her grandfather--and her Hollywood dreams. After her grandfather dies, he leaves her a strange gun known as the Eto-gun that has mystical powers linked to zodiac animals. She decides to pack up and take aim at her goal of stardom. On the road to tinsel town, she learns about another gun called Zodiac, which is Eto's twin. The two firearms share a powerful connection, and an underground organization will stop at nothing to lock and load on the guns' secrets...
