Charlotte isn't like other sheep. She is brave and adventurous and likes to explore where no sheep has explored before - unlike some sheep, who just prefer to brag about how mean and tough they are. Then one night, a terrifying howl echoes from the forest... the kind of howl that could only be made by a wolf. The boastful sheep run away and hide. But Charlotte is made of sterner stuff. Who will save the day... and who will end up looking sheepish?
