The story of the factory worker Pietro Perotti, who worked at Fiat Mirafiori from 1969 to 1985 and participated in the workersâ protests by overseeing communications inside the factory, making stickers, wall posters, texts and drawings in the bathrooms, figures out of papier-mâchĂŠ and foam rubber, and turning the protest marches into âstreet theatre.â With his movie camera, Perotti immortalized the situations and workersâ protests at Mirafiori until 1974. Thanks to this unpublished material, the movie paints a fresco of factory life in what used to be Europeâs biggest metalworking factory.
