Synopsis
Holly has gradually gotten used to having a hearing aid and is slowly getting to grips with her new super hearing. So when her classmates' belongings suddenly start to disappear on the school camp trip, Holly sees it as her duty, like a true superhero, to solve the mystery.
But even with super hearing, Holly obviously still has to learn to listen - mostly to herself. The thing is: nothing goes as planned, and suddenly Holly herself is accused of being the thief.
With the help of her best friends, Jose and Magnus, Holly must do everything to find the culprit and, not least, get an answer to the question: Who wants to get to them - and why?
