Die zertanzten Schuhe (2011)

Twelve princesses sleep in twelve beds in the same room; every night their doors are securely locked, but in the morning their shoes are found to be worn through as if they had been dancing all night. The king, in mourning, promises his kingdom and a daughter to any man who can discover the princesses'secret within three days and three nights, but those who fail within the set time limit will be put to death.
