In the Tennessee mountains lived two families, the Blakes and the Morgans. A feud has existed between these families for two generations, but the bitterness has subsided somewhat until one day Blake's dog wandered on to the land owned by John Morgan. He promptly shot and killed it, delivering it to the cabin of Blake with a note that stated he would kill "any two or four legged dog of a Blake that he caught on his land." The feud was again renewed. Jim Blake left his cabin with the avowed intention of killing Morgan, but was persuaded not to do so by Margaret Dunn, the little schoolteacher of the valley. She persuades him to return with her to her little schoolhouse where she presented him with a Bible showing him the fifth commandment "Thou shalt not kill." He agreed to read the Bible and try to learn its teaching. One day while posting a notice of the meeting at Sunday School, Margaret encountered Jim Blake on his way to the village store. Morgan was down there waiting for him. Margaret realized what it would mean if they met so she followed young Blake and once again prevented bloodshed. Sunday came and the school was crowded. Blake came because he loved Margaret. Morgan's child also attended but Morgan learned of this and his hatred for Blake brought him to the schoolhouse with a loaded rifle. He fired through the window intending to kill Blake, but Morgan's child came between and received the bullet. She was carried to the home of Blake and a physician summoned, who declared the child could not he moved. Morgan learned of his mistake and full of repentance he went to the Blakes and begged them to shoot him. Jim prevented his father from fulfilling his threat to kill Morgan, by throwing up the pointed gun, when the physician announced that the child could not he moved or he would not answer for its life. Morgan pleaded that it remain there. William Blake seeing the complete surrender of his bitterest enemy finally agreed and the feud was declared at an end. Later the little schoolteacher surrendered to the love of her former pupil, Jim Blake.
