Former big city detective John McBride is an easygoing man until a cold-blooded town sheriff warns him to mind his own business, or face a lynching. Driven by his sense of justice, McBride takes on the sheriff, an evil mayor and his cruel psychotic son, and a small army of hired gunmen. Helped by a mysterious white-haired, quick-drawing preacher, McBride shoulders a task most men would flee from. But John McBride isn't most men.
