In the gloom of an old house, where childhood memories mingle with the fog of oblivion, whispers the legend of the Ghost Puppy, a story that defies logic and confronts us with the fragility of our perception. A boy, playing in his room, hears the scratching and whimpering of his puppy at the bedroom door, where he had left him locked moments before. Hurriedly, he opens the door, hoping to find his faithful companion, but the room is empty. Confusion seizes the child. Where has his puppy gone? How could he have escaped from a locked room? The anguish intensifies with the return of the father and brother, who arrive home with the puppy, as if nothing had happened.
