Däumelinchen (2013)

Seven-year-old Anna does not understand the adult world, which, from her perspective, consists solely of frustration and prohibitions. Above all, she cannot grasp why she is no longer allowed to suck her thumb. Instead of accepting these restrictions, she decides the time is ripe for a revolution. Anna wants to change the world and convinces the adults to cast aside all rules and behave like children. But can such an idyllic vision of the world possibly work out?
