When the spotlight flickers and the music screeches to a stop, what was supposed to be the biggest dance of the year turns into a full-blown catastrophe.
Vivi, 10, and her younger sister Ellie, 8, are no ordinary girls. They are Agents of Mystery, chosen by a magical compass that never points north, only toward trouble. With their loyal canine partner, Officer Tato, at their side, they specialize in solving puzzles no one else can untangle.

But this time, the clues are hidden beneath glitter, backstage whispers, and a suspiciously slippery stage.

On the night of the Spring Showcase, costumes vanish, props collapse, and the grand finale almost ends in disaster. Is it sabotage? A jealous rival? Or something even more unexpected lurking behind the curtains?
With time running out and the audience waiting, the sisters must decode secret messages, follow a trail of sparkling clues, and uncover the truth before the final bow.

Because when the music stops… Agents of Mystery step forward.
