About the title
A young gymnast lives in the small town of Brembate di Sopra near Bergamo, dreaming of a career in sports; she trains hard and spends all her free time in the gym to improve her performance. We see her walking home late one evening, and then the news reports her disappearance. Prosecutor Letizia Ruggeri takes on the investigation; the child is actively searched for, and a suspect even emerges in the case, but he is quickly released. Three months later, her body is found near the town, and forensic investigators obtain a DNA sample from the likely killer. Letizia decides to organize a large-scale collection of DNA samples from the local population, and many criticize her approach to the investigation.
