De fantasievolle June ontdekt een pretpark genaamd Wonderland, dat verborgen zit in het bos. Het park beschikt over leuke glijbanen en pratende dieren. June ontdekt al snel dat het park uit haar eigen fantasie is ontsproten en dat ze de enige hoop is, samen met de dieren, om deze magische plek te redden.
