On May 9, 1978 Aldo Moro, president of the Democrats, and Peppino Impastato, a young communist militant killed by the mafia, lost their lives a few hours apart. Enzo, Vittorio and Antonio, three conscripts, have been working for weeks at a roadblock along a road where not a single soul passes. Younger Brothers is the story of that May 9, a long day that will change Italy forever.
