The four Tuscan friends now are over sixty years of age and are nearing retirement. Count Mascetti is always the most unfortunate because in addition to end up in a wheelchair has also lost his wife in a road accident. So his friends to not make him suffer the persuade him to move into in a retirement home, where, however Mascetti never ceases to make his jokes to patients and nurses, with his "supercazzola". Soon after that, the architect Melandri and the barkeeper Necchi join him at the retirement home and take part with him in playing pranks to the other elders. In particular, the man targeted by the three, (also to include the surgeon Sassaroli), an old man (played by Bernard Blier) who dreams about his youth, the four friends give him well-served setting up a scene similar to the wastelands of Hell. There is the old man and conducted with a subset of satanic ritual in which Sassaroli plays the priest and a prostitute is very young sacrificial victim, believes young again. In fact, the four friends pranksters and goliardic have painted the hair black man after he fell asleep. The next day the old man feels like reborn and starts to make a lot of exercises dangerous for a man of his age, dying of a heart attack in a short time.
