This film has no fiction, but a lot about the reality of gender violence. A teenager disappeared in Bergamo, a city in northern Italy, capital of the homonymous province and part of the Lombardy region. In fact, she was kidnapped by the end of 2010, weeks later she was found dead in an open field on the outskirts of Bergamo. That shook Italy, so the police took the task of investigating the incident with very little chance of discovering the culprit, unless the necessary resources were put in place for this purpose and develop a thorough investigation. This was what the prosecutor Letizia Ruggeri set out to investigate for years and with traditional methods. Fortunately, we live in a world where there is scientific development in the field of molecular biology; it is known what a gene is, a short segment of deoxyribonucleic acid (DNA), and an important part of the chromosomes. They tell us as a whole the hereditary material of the human body and the way it works. Therefore, there was no need for the services of Sherlock Holmes or detective Philip Marlowe. The film clearly shows the political baseness and the entanglements of an opposition to harm those responsible for the investigation, and as usual, without proposing any other alternative to get the truth of the case.
