The journalist and writer will take viewers on a thrilling journey through a crucial day in history, a day that marked or changed the course of events. The first episode starts with Adolf Hitler's trip to Italy (3 May 1938) which, behind the celebration of the friendship between Benito Mussolini and the Führer, will allow us to analyse in detail the relationship between the two dictators. And also the Five Days of Milan (18-22 March 1848), the insurrection in the then capital of the Lombardy-Veneto Kingdom, which led to the temporary liberation of the city from Austrian rule and a prelude to the Risorgimento. There will then be an episode dedicated to Caterina de' Medici - Italian Queen of France - and one of the bloodiest and most controversial days of the Renaissance: the night of St. Bartholomew and the massacre of the Huguenots in Paris (24 August 1572). In Pier Paolo Pasolini, the Last Night (November 2, 1975) the story of a brutal and cruel murder will be addressed, destined to become one of the great mysteries of post-war Italy. Other episodes of “A Special Day” will be dedicated to the Liberation of Italy and Europe from Nazi-Fascism (June 1944 - The Americans Are Coming), to the terrible eruption of Vesuvius, which in 79 AD destroyed Herculaneum and Pompeii in The Last Hours of Pompeii, to the death and life of one of the greatest painters of all time, Michelangelo Merisi da Caravaggio in Caravaggio - Crime and Punishment, to the Fall of the Eastern Roman Empire which marked the end of the Middle Ages in the episode entitled Constantinople - The Fall of the Empire, up to the institutional referendum with which Italians chose what form to give to the State after the end of the Second World War in the episode June 2, 1944 - Monarchy or Republic. Finally, the last episode, The Great Beauty, is a tribute to the ingenuity, creativity and genius of artists, architects and artisans who, over the centuries, have transformed our country into an open-air museum, unique in the world. A visual and emotional experience that recalls the immense value of our heritage and its importance in the global cultural panorama. Aldo Cazzullo - accompanied by two correspondents in "history", Claudia Benassi and Raffaele di Placido - travels through the places of these special days, wonderful and "speaking" places of Italy and the world: from the Baroque Rome of Caravaggio to the rationalist architecture of the Foro Italico; from the Teatro alla Scala in Milan passing through the Paris of Caterina de' Medici, the Sassi of Matera where Pasolini filmed The Gospel According to Matthew, Normandy for the landing of the Allies, the Archaeological Park of Pompeii up to Istanbul, ancient Constantinople, at the center of the stage of history. To enrich the story, through the episodes, interviews with Furio Colombo, Walter Veltroni, Riccardo Muti, Paolo Guzzanti, Francesca Fagnani, Giancarlo De Cataldo, Dacia Maraini, Francesco Guccini and Corrado Augias. “Una giornata particolari” is an original format of La7 produced by Stand by me.
