When his uncle passes away, Holliday discovers a medieval sword-wrapped in Adolf Hitler's personal battle standard. But when someone burns down his uncle's house in an attempt to retrieve the sword, Holliday realizes that he's being drawn into a war that has been fought for centuries-a war in which he may be the next casualty.
