Four young detectives race to save a desperate little girl from getting shipped off to boarding school by her monstrous step-mother in this family friendly mystery adventure from the makers of Clubhouse Detectives. Anna McKenzie is a seven-year-old girl with a big problem: her evil step-mother has hatched a plan to ship her off to boarding school until she's 18, and send her beloved canine sidekick to the doggie prison. In a last-ditch attempt to reach her beloved grandmother before it's too late, Anna attaches a note to a helium balloon, and watches as her plea for help floats up into the clouds. When the message reaches 10-year-old Gage Williams, the young boy gathers his detective friends in their floating clubhouse, and together they hatch a plan to break Anna free. It's a big task for such young detectives, but if Gage and his pals can find a way to get Anna away from her step-mother and back into the arms of her grandmother, there's no mystery this determined team can't solve.
