After accidentally injuring a friend in a wrestling match and swearing off violence of any kind, Dr. Hart becomes the physician at Big Creek Mines. While most of the miners respect him one bully taunts both he and the young schoolteacher he has taken a fancy to. Mindful of his eschewing violence he ignores him but when diphtheria breaks out in camp, the physician proves himself a hero and his greater strength stands by him in many ways. The first to fall ill is the bully's little child and the man becomes frantic at the thought of losing her. Thinking the doctor will allow his daughter to die to get even with him he tries to prevent the use of a serum needle, but the doctor uses his great strength to quickly overpower and bind the father saving the child with the shot.
