In the middle of a field of grain lives a little Harvest Mouse. Lonely, he has come up with a nightly ritual of singing a lullaby to the moon. In exchange, the moon watches over him until he falls asleep. But one evening his faithful companion disappears and is nowhere to be seen.

The mouse is surprised to discover that other animals, including a duck, a squirrel, and a rabbit, are also missing the moon. They begin to blame each other but when they take refuge from a storm in a cave, they apologize to each other. When the moon reappears, they all realize that it is not their possession but something precious shared by all. And by disappearing, the moon has made it possible for the mouse to make new friends. A final lesson is that worry never gets one anywhere except in more trouble.
