Mary Kathryn is a small girl who wants to have a "Good Eye" just like her engineer father. She loves exploring the natural world and finding VERY IMPORTANT THINGS to show her father-like seashells, pinecones, and pebbles. But when Mary Kathryn's observations begin to cause trouble, she starts to wish she didn't have such a Good Eye after all. It's up to Daddy to help show her the beauty and meaning in all the things she's discovered along the way.
