Don Gregorio has a peaceful job: showing flats to potential buyers. One day, he has to show a flat that, to his surprise, seems familiar somehow, and for good reason, because it's the flat where he used to live when he was a child. In one of the bedrooms he finds a picture that he himself drew on the wall years ago, a portrait of himself when he was little. The picture of Young Gregorio comes to life and invites Don Gregorio to travel to a fantasy world where he will rediscover the emotions, the desire for adventure, the warmth of family life and a whole host of feelings he had almost forgotten. And on his return to his current home, Don Gregorio is newly aware of the how important family and Señor Valentín are. As a result, it will be Gregorio's turn to invite Valentín to travel to this fantastic place.
