Sterling North is a tender-hearted boy, who loves animals very much.
One day Sterling finds a baby raccoon in the woods. He names the raccoon Rascal and takes it home, where the baby raccoon becomes Sterlings constant companion.
Rascal grows up very well. Everything seems to be going well, but one day Rascal gets a taste for sweet corn and begins to raid the neighbors corn gardens during the night. Sterling realizes that it is truly difficult for men and wild animals to coexist in the same place.
One day a misfortune befalls Sterlings family. His fathers ranches are entirely destroyed by a heavy rainstorm.
Sterling must go to Milwaukee to attend junior high school. Rascal is now a young adult. Sterling decides to return Rascal to his natural life in the woods.
Sterling goes to a lake with Rascal in his canoe and sets him free in the woods. Next day he leaves town alone on a train bound for Milwaukee.
