After an altercation with a gang that leads to the accidental death of a young boy, China resigns from the force, and returns to her hometown of Beaver Creek, Utah. On her way into town she runs into her former high school sweetheart Matt Conroy. Searching for her father, she goes to the Beaver Creek Inn and encounters a hostile situation, as her father has just arrested one of the men there. Her father, John O'Brien, is the town sheriff. China finally catches up with him back at the station. John is losing control of the town to local crime boss Edwin Sommers, who controls corrupt deputy Marty Lickner and corrupt local judge Harry Godar.
