Lotta just cannot wait for her first school trip. But then it is not just Chanell, Cheyenne’s little sister, they have to take with them but also Lotta’s father volunteers to accompany the class as a chaperon! To make things worse, their new French classmate Rémi has a huge crush on Lotta. And as if that was not already bad enough, the youth hostel seems to be haunted: rooms disappear, Chanell disappears, and there are stories about a girl lost in the sand dunes. Are there any connections to an old legend of a poltergeist? Fortunately, there is Lotta´s gang the “Wild Rabbits” – you can always rely on them.
