When a new boy named Johnny Johnson arrives at school for the first time, Laura is immediately smitten. Johnny is a friendly boy and although oblivious to Laura's crush on him, he certainly makes it clear that he is interested in Mary. Even though Mary does not share the same feelings, the "love triangle" is enough to cause tension between the sisters.

Laura connects with a sweet, shy classmate named Olga Nordstrom, who happens to have been born with a short leg. Charles has an idea that can change Olga's entire life, but the challenge will be convincing the child's stubborn widowed father.
