'Il Principe' tells the story of Vittorio Emanuele di Savoia, the last heir to the throne of Italy. He was a top model, a prince in exile and someone who changed the lives of many. Although the trial for the murder of the young Dirk Hamer in 1978 is central to the life of the prince, the series also reveals more intimate events, such as his difficult relationship with his parents, his love story with Marina Doria, his years in Iran and his scandals .
