In a decaying, rat-infested town gripped by greed and corruption, a mysterious stranger arrives with a haunting flute and a simple offer. Directed by Ji?í Barta and featuring the voices of Old?ich Kaiser and Ji?í Lábus, this darkly fantastical thriller reimagines the classic fable with a chilling, adult edge. The townspeople, led by a scheming mayor, eagerly hire the enigmatic Piper to rid their streets of a grotesque plague of vermin, promising a fortune in gold for his services. Yet when the prosperous but treacherous citizens betray their oath, they awaken a far more ancient and terrifying power than they ever imagined. As the Piper’s melody shifts from a promise of salvation to a tune of grim retribution, the community must confront the monstrous cost of their own avarice. Blending stunning, macabre animation with a tense, atmospheric score, this is a gripping tale of broken promises and supernatural vengeance, where every note played carries a deadly price.
