Set in Italy in the 1970s, VALLANZASCA is the true story of the Italian underworld’s most infamous outlaw. A criminal by age 9, Renato Vallanzasca grew up to become the country’s most notorious mobster before the age of 27. Vallanzasca and his gang wrested control of the Milan underworld with a string of high profile robberies, kidnappings and murders. In the process, he captivated the public and earned the nickname ‘il bel Renè’ – for his devilish charm and handsome face. Arrested multiple times, his daring escapes from prison enraged the government, angered his rivals and fed his legend.

The theatre company managed by Marco is passing through a crisis; the big networks invaded the market with their poor products and they lay down the law. Marco finds an important subject to work on: homosexuality; but it is hard to ask Federica, who is a writer and director, to work on it. That subject is a thorn in her side, as it was the cause of her marriage break up. Federica angerly refuses Marco's proposal, but after one night of searching, spent on Internet, she brings to light an aspect of the homosexuality, which doesn't want to give up, now: "The Pink Triangle" that means homosexuality as a martyrdom, the tribute of blood that homosexual people shed during the nazi period. Federica explains Marco and other actors of the company the new project, by telling the historical documentation. Each of them imagines his own character in dark colour performances, often brutal, following the line of blood that history has drawn.
