Jacinto, a former bullfighter who lives miserably with his nephew Pepote, receives a letter reminding he, as agreed a few days before, he should go to a bullfight to be held that evening at Las Ventas. The letter infuriates Jacinto who thinks this is a joke, since he retired from the arena for years, has not signed any contract. When Jacinto is located around the square, picking up cigarette butts that pull the audience, make sure the letter was not a joke, because his name appears on the poster.
