Everyone needs a friend, even a tiny Shetland pony named Princess. One
day, she manages to escape from the paddock where she is stabled with her
mother and sets off on a mission to find someone to play with. She has
various encounters with other horses, as well as lambs, goats, donkeys and
mules. Because she is so small, all the horses she attempts to befriend
regard her with contempt, and the other animals want nothing to do with
her. She faces dangerous situations, learns lessons that all children will
take to heart, and finally becomes a heroine whom everybody wants to play
with.
