During a thunderstorm, lightning strikes the ramshackle amusement park of Tammi’s late grandfather Jackel and strange things start to happen. Three figures in the park’s ghost train – Rumpelstiltskin, a giant and a witch – come to life and begin wreaking all kinds of havoc with their wondrous, magical powers. Teenagers Tammi, Umbo and Keks have their hands full trying to save the amusement park and also bring the dysfunctional family back together again.Director Thomas Stuber’s first family film after such productions as In the Aisles and Dark Satellites is inspired by the eponymous cult TV series broadcast in the former GDR from the end of the 1970s.
