On 16 January 1977, a Sunday, the Ranza family gathered with friends at Morosolo, above Varese, to have lunch together and ski down the slope below the house. After eating, a snowball fight begins: or perhaps it is the filmmaker Stefano Ranza who asks the boys and friends to start playing. His son Guido recounts that his father 'preferred moving scenes, he always made us children run'. A few kilometres away, in Como, a child, the son of a small industrialist, was kidnapped from his parents' car the night before. Who knows if, under the apparent carefree attitude, the Ranza parents, Lombard entrepreneurs, look at their boys with fear for the future.
