In the heart of the Heartforest a small, cute unicorn is born. But although everyone lavenderously loves it very and feeds it with sugared lucky clover all the time, the little animal does not behave like a unicorn at all. It simply always says no, so that its family soon only calls it uNOcorn.

One day the uNOcorn escapes from its cotton candy world. It hits a raccoon who doesn't listen, a dog who doesn't give a hoot, and a princess who always knows better. These four make a pretty good team. Because even being stubborn is much more fun when you're together!
