On a cold winter's eve, deep in the woods, a mother shrew frets about her sick young son. His head is cold and his feet are hot, and there is only one thing that can cure him: wild honey from the moon. Mother Shrew does not stop to wonder how she will make such an impossible journey. Instead, she grabs her trusty red umbrella, gives her darling son a kiss, and sets out into the unknown. Along the way, Mother Shrew encounters one obstacle after another, from a malevolent owl to a herd of restless "night mares" to an island humming with angry bees. But each can prove no match for a mother on a mission.
