Primo Spaggiari is a small cheese factory owner from
Parma. Primo is of peasant origin and did not go beyond elementary school, so he is considered a
self-made man. His wife Barbara, on the other hand, is a refined woman of
French origin. One day, their son Giovanni is kidnapped by a group of terrorists and Primo has to raise a billion
lire for the ransom. Meanwhile, the dairy he owns is hit by a serious economic crisis. A young worker, Laura, Giovanni's girlfriend, and a worker priest, Adelfo, who know a lot about the kidnapping, intervene in the story. From them, Primo learns that his son has died. Primo, however, continues to collect the money, helped in this by his wife, to save his second creature: the factory, on the verge of
bankruptcy. Following the instructions of a false letter, written by Giovanni's girlfriend, the couple deposits the ransom money in the indicated place. The sudden reappearance of Giovanni means that in the end the billion lire is invested in the dairy, transformed into a cooperative company, under the control of the workers. ==Cast==
