A mother practically mute. Forty years earlier, a militant of the extreme left killed his father – a deputy police brigadier in his twenties – during a political demonstration. Maria was born two months later. One day she learns that her father’s murderer has a name, a face, a job. She served his time and lives in Milan. «Now I know who to hate», Maria thinks. She dyes her hair and takes a fast train to go and meet him. She carries a gun.
