Coals of Fire treats of two men, one a big, strong, brawny fighting man, the other, a man weaker in physical vitality, but superior in his intellectual mentality. The latter. Noel Clayton, loved a girl of the old Kentucky border, but he was forced to see her carried off by her other suitor, Bill Ewing, the man of brawn. Noel saves the life of Lucy, the little sister of his loved one, and later goes away to the settlements to study law. Years afterward, Bill kills a man and is about to pay the penalty when Lucy, now grown to womanhood, appeals to Noel, the rising young lawyer, to save Bill for the sake of his former sweetheart. He returns good for evil and frees Bill, and finding in Lucy a tender and loving replica of her sister, marries her. Future years bring him fame and power and eventually he becomes governor of Missouri.
