The documentary is about the foundation of a new town in the province of Oristano: Mussolinia. Named Arborea after 1945, it was founded as a result of a dike’s construction in the Tirso basin. The film shows the vastness of the dike in details. Forty thousand hectares of Campidano were made suitable to settlement thanks to hydroelectric plants, and the hard work of plowing and sowing the fields. The images show the efforts of building up a city from nothing to the first farms and houses, the road network and the new church. The last frames are in a street market: the display of goods to be sold and the faces of women doing their shopping.
