When a lightning strike starts a fire in the barn, Callie’s small size becomes the key to saving everyone. The animals cannot reach the latch on the barn door, but Callie is small enough to climb into the panel and push the lever. With Flossy’s help and encouragement from her mother, Callie unlocks the door, allowing every animal to escape the burning barn safely. Her courage proves that sometimes the quality that makes someone different can become their greatest strength.
