A young man stumbling through the forest on a winter night finds a crane caught in a hunter's trap. Against his better judgment, he frees the injured bird and watches it disappear into the darkness. That same evening, a beautiful woman appears at his door, seeking shelter from the cold. She becomes his wife, and for a time, they live in quiet contentment together. But she guards one room fiercely, forbidding him from ever looking inside. Curiosity gnaws at him until finally, unable to resist, he peers through a crack in the door and discovers the truth: his bride is not human, and her greatest gift comes at an unbearable cost. What begins as a debt repaid transforms into a tragedy about the distance between gratitude and greed, about what happens when love demands a sacrifice too terrible to ask. This puppet animation weaves a timeless folktale into something both delicate and devastating, where magic carries weight and every choice has consequences that echo beyond redemption.
