The documentary narrates about Bologna, about doing politics in Bologna, from 1945 to 1977. The narration of the film goes on sometimes by evocations, sometimes by pointing out historically important phases in the political, social and cultural life of the city. A city which rapidly went out the reconstruction phase and became a national guide in the creation of an economic development model based on small and medium enterprises, on distribution and production foods consortia, on building mutual companies and local banks. On the other side, Bologna put fore-front social services in the field of elderly persons cares, of family and children sustains, with a great efficiency in the health care and in the public green safeguard. Bologna was the ex-partisans’s and anti-fascist’s invention of a possible city: livable, lively, supportive and comfortable.
