With all his faults, Jack Martin, an Arizona gambler, has one redeeming quality, a deep love for his motherless child. The baby is taken sick. Leaving her with Aunt Jane, the Mexican housekeeper, Jack goes for Dr. Winton, who is also the sheriff. The child dies. Crazed with grief, Jack gets drunk and shoots the town marshal. Leaping astride his horse, he escapes into the desert. Far out on a sandy plain, he comes across the dead body of a young Apache squaw, who has been bitten by a rattlesnake. By the side of the lifeless form he finds a child who has nursed from its mother's breast and imbibed the poison. Jack thinks of his own child, and his heart goes out to the little one. Jack has eluded his pursuers and his horse has dropped from exhaustion. He knows that he is free to escape. He hesitates, but determines to save the little papoose by doubling back on his tracks and meeting the posse, of which the doctor-sheriff is the leader. On rounding a curve in the canyon, he comes upon his followers, who cover him with their weapons. Holding out the child to the doctor, he begs him to do something for it. The sheriff examines it and discovers it is dead. Jack, with tears in his eyes, stands ready for his capture, conscious that inasmuch as he did it for one of God's little ones he has not done it in vain.
