Tommy is too little for many of the things he wants to do. Then one day an infant falls into an abandoned well at the neighborhood park, and none of the adults can reach her. Tommy volunteers to be lowered into the well but the chief firefighter says he cannot let little children risk their lives. Tommy and the gathered parents convince him to change his mind. When the difficulty of what will be involved becomes apparent, Tommy has second thoughts and struggles to summon the necessary courage.
