Ruth and Tom take a summer cottage at Lake Osago, near Cheslow, and plan to spend the summer relaxing with their new baby, June. Both Ruth and Tom feel jittery and overprotective of their baby and worry over every odd noise. Ruth's worries deepen when Ortiz Coronda arrives at the Cameron cottage, asking to see Ruth. Coronda was one of the Mexicans who recently kidnapped Ruth, and Ruth fears that he is up to his old tricks.

Ruth reluctantly meets with Coronda, who informs her that he has reformed and has recently inherited a large sum of money. Coronda asks Ruth to work for him in his new moving picture company. Ruth declines, hoping that Coronda will disappear. Ruth notices Coronda hanging around her baby's nurse, Anita, and worries about his motives. One night, Anita disappears -- along with Ruth's baby!

Ruth is certain that Coronda is responsible and that he and Anita planned all along to abduct the baby. After Ruth and her friends can find no trace of Coronda, Anita, or the baby, they wonder whether they are on the wrong trail. Ruth fears that she will never see her baby again.
