Roberto, 40 years old, is an expert in computer security who lost his wife when she gave birth to their second child Sara, who is now 7. Laura is an investigative journalist who has been shaken by an experience lived in Somalia that made her choose to dedicate her life to fight against the horrible disappearing of children. A spring morning Roberto drives his daughters to school. Feeling guilty of having reprimanded Sara, he stops to buy her a toy. Anxious to repair the damage, he forgets his phone in the car and the eldest daughter Asia runs after him bringing the mobile and leaving the little sister alone. After a few moments, little Sara is missing. Investigations start, and they are conducted by the police commissioner Mancuso, a man who always fully trust in justice. In the meantime Laura offers Roberto her help to find Sara. She explains the silence of medias and UN States about disappearing children, and shows irrefutable proofs of what she says. Her presence is not pleased by the commissioner who tries everything to push her away, believing that Laura is a paranoiac who tells of unfounded theories. But Laura is the one that offers the commissioner the first proof that leads him to the arrest of a kidnapper and to the finding of some missing children.

Laura finds a drawing in one of those children’s pocket, and shows it to Roberto: that was surely drawn by Sara. After a few days Asia sees the drawing and returns to hope for her sister. Sara has drawn geometric shapes from a nursery rhyme, and each of these is a clue. At the same time the commissioner is being suspended by duty, just right before the arrest of an exponent from the high finance. Roberto doesn’t know what to do and asks advice to Laura, for which he has a crush. She suggests to do what any parent would do when they came less of the most important thing they had. In way to demonstrate her determination, Laura plays her last card and obtain the contact of the broker, the man who arranges the moving of children kidnapped in Italy on behalf of other european countries. The day after the television news announces the alleged suicide of Laura, and the thesis is strengthened by a perfectly planned strategy of discrediting. Roberto now knows that the news is yet another hoax told to confuse people, to give a different version of the truth. He knows for sure it is murder. Having lost the most precious thing to him and made blind by fury, Roberto decides to gain justice at his own way. The commissioner, now aware of how law is useless against the powers, makes his best to cover Roberto’s actions: the fury has transformed in revenge and he left a bloody trail behind. After Sara has been declared dead, she is found alive in a former convent in a sicilian village.
