Tooth is a young, feisty Tooth Fairy, who lives in Fairytopia, the magical land of the fairies. One day, fed up with the way most fairies have forgotten how to use their magical powers, she decided to stir them up and have a bit of fun. Her plans however go horribly wrong and two days before Xmas she manages to make Fairytopia bankrupt. When Tooth finds out how much trouble she's in, she realises the only person who can help her is the one and only Mrs Santa Claus, who disappeared over 100 years ago. Teaming up with two children, she sets off on the adventure of a lifetime. Pursued by the evil Plug, a terrifying fairy hunter and his posse, the race is on to save the world before Christmas and Easter are ruined forever.
