Frost and Hancock are ex-Confederates who, with the help of their henchmen, are plotting the assassination of former president Ulysses S. Grant. They're scheming to lure Grant to Mountain Springs by inviting Matt Tyler, the man who saved the general's life during the war, to come work for their law firm. Greeted by the brutal murder of a law clerk, Matt can immediately smell trouble in the air. With allies such as Jennifer White, who has incurred the constant ire of the firm with her blazing newspaper editorials, and a black veteran, Matt sets out to save Grant's life a second time and bring peace to the fractured town.
