A monster has broken into Jack's garden and stolen his favourite yellow underpants. The cheek! Jack sees his chance to flex his new fairy skills and embark on his first ever solo mission. Unfortunately, in chasing the creature across town and leaving a trail of chaos in his wake, Jack breaks every rule in the fairy rule book (you must keep the magical kingdom a secret from humans, no one can know you are really a fairy, and you must NEVER EVER cause a lorry to crash into a take-out restaurant shop, creating a ketchup spillage across the high street whilst in pursuit of a magical creature who has your pants).Will Jack get his wand back, track down the monster, and make everything right again before he's kicked out of the magical kingdom for good?
