Alpacas on Amrum? Lotta is super excited about the class trip to Amrum. But then, unexpectedly, not only Cheyenne's little sister Chanell comes along, but also her dad – as a substitute teacher! Oh man. As if that weren't bad enough, something is also wrong with the youth hostel. Rooms are disappearing, Chanell goes missing, and then there's that creepy photo of Mieke, who seems to be haunting Lotta. But luckily, there are also two alpacas (oh wait... llamas) on the island, plenty of sand, and above all, the wild rabbits, who are always reliable.
