Mid-1980s. Aida is 12 years old and has long known that there is something dark about her father Adriano: his repeated and prolonged absences, his frequent trips around Europe and his work in an unspecified import-export company don’t add up. When she meets Daniel, his new schoolmate and aspiring photojournalist, she realizes that perhaps it is time to look into the matter. The two kids turn themselves into detectives and begin a meticulous investigation that involves all of Aidaʼs relatives, in a search that combines family events with the crime stories that characterized Italy between the 1970s and the 1980s. Adriano, in the childrenʼs minds, thus becomes once a red terrorist, then a killer, a P2 Freemason, a spy, a fugitive… Until one day the investigation comes to an end.
