Joe Beck has lost the love of his life thanks to a Pixie's Curse and he now needs to figure out how to get his girl back, learn more about the mysterious Pixies and undo a bad deed he did long ago.
Every year, the elves come from his magical world to bring humans a new spring. Tim is a new one this year. Distracted by the attractive sound of the fair, he wanders away from the other elves, being captured by former trapeze artist Samuel, who brings him to Vladimir, owner of a circus who exploits him as a fairground attraction. Teresa, a naughty 6-year-old girl, is jealous of her little brother, baby Jon. When visiting the fair, she discovers Tim while he is being exhibited and she will become infatuated with him. Tim, at the same time, will see in her an opportunity to escape. Hidden in Teresa's house and protected by her, they live several adventures, becoming inseparable friends. Over time, matching with the end of the spring, Tim begins to transform in a Little tree. He has been away from his world and his people for too long, and only by helping him to return will Tim be saved. There is no time to lose, but be careful Vladimir is lurking.
