Hinko stares at his new limbs and cannot believe his eyes. His wife Justina fixes her glasses to better see what had happened to her husband. Both look at the place where, according to all the rules, his legs should have been. They, however, are now replaced by a single fin. Hinko phones the city doctor to attend to him. Doctor is not surprised at the sight of his new limb, as he is not the first person to have it. Undeterred, Hinko follows his morning routine and walks his dog. He traipses, or rather clumsily swims out into the street, and looks around with a bewildered expression. The street is flooded and townspeople are happily swimming along the sidewalks. He joins a crowd of people in the main town square, where a journalist is talking to the famous promoter of fins, Dolores. Hinko returns home. He is quite upset. His wife seems to have succumbed to the new fashion. As the water around Hinko dangerously rises, he tightens his grip on the armchair further.
