From NetFlix:
In this taut drama based on a true story, 17-year-old Rita (Veronica D’Agostino) is leading a privileged life when her father and brother are slain by rival Mafiosi. Bent on revenge, she turns to a sympathetic magistrate (Gérard Jugnot) and breaks the code of silence. In her journey from self-centered teenager to fearless advocate for justice, Rita enrages Sicily’s most powerful men, putting her life in jeopardy.
Probably the biggest impression I got from this amazing enactment of a true story was how all-encompassing and soul-destroying is the Mafia cult. For Rita the real stumbling block was accepting the fact that her adored father was no less a brutal and cruel assassin than all the other animals. Her own mother did her best to convince Rita to not testify even though the Mafia had killed Rita’s father and brother.
Also awe inspiring was the bravery of Rita and the prosecutor and all the other law enforcement staff. Human life means nothing to the Mafia.
Be prepared for a surprise (and true) ending.
