In a picturesque medieval village, the inhabitants face an unimaginable crisis: a rat infestation has taken control of their streets and homes, ruining crops and endangering the health of the place. Desperate, the villagers seek a solution, and a mysterious piper appears with an unusual proposal. This enigmatic character, with magical abilities to play his flute, promises to eradicate the rats in exchange for a generous reward.
The villagers, skeptical yet with no options, accept the deal. With the hypnotic sound of his flute, the piper manages to lure the rats toward the river, where they disappear from the village's life. However, when the time comes to pay, the villagers, greedy and ungrateful, decide that they are no longer willing to keep their promise. This infuriates the piper, who, in retaliation, uses his magic to take vengeance on the ingrates.
In an unexpected twist, the piper hypnotizes the village’s children and takes them to an unknown place, leaving the adults plunged into chaos and regret. This dark fable serves as a critique of selfishness and ingratitude while exploring the nature of revenge and the importance of keeping promises. As the story unfolds, the villagers must face the consequences of their actions and find a way to recover what they have lost, confronting their own demons and the lesson the piper has to offer.
