The film is based on the real story of the last days of Stefano Cucchi, a 31-year-old building surveyor who died in 2009 during preventive custody, victim of police brutality.

[2] On the evening of 15 October 2009, Stefano Cucchi, a young building surveyor, is brought to Regina Coeli prison in Rome after being found in possession of some packs of hashish, 2 grams of cocaine and a pill of a medicine for epilepsy.

This brings his family, led by his sister Ilaria, to start a battle for the truth and to try to find the people responsible for Stefano's death, once they realized, looking at his corpse in the morgue, that he has been savagely beaten.

In their son's apartment, Stefano Cucchi's parents found over a kilo of hashish and 130 grams of cocaine, which they reported to the police straightaway.

After Stefano's death, Ilaria Cucchi, his parents Rita and Giovanni and lawyer Fabio Anselmo embarked on a fight for the truth.
