Two old persons have raised their son's child because his wife was of the child-hating kind. When the girl is 10 years old, her mother returns and means to take her away. The girl is reluctant to go, having grown attached to her grandparents. Numerous complications ensue, and it is finally determined which is thicker, blood or water, when the grandfather saves the child from the hands of a gang of crooks who had planned to teach her the "art" of picking pockets.
