In the heart of Rome, the Tiber flows silently, often ignored by its inhabitants. Four stories intertwined by an invisible thread: love for the Tiber, its memory, and its soul. Giulio lives on a floating barge, and with a thousand experiences on the Tiber, he has made the river his life. Carmen has dedicated her life to protecting the sea and the Tiber, and devotes herself daily to cleaning it. Cesare, the last eel fisherman, has spent his entire life on the Tiber, keeping alive a tradition that is disappearing. Finally, Gregorio, a solitary shepherd, lives on the riverbank, almost an echo of its abandonment. Through these narratives, the Tiber emerges not only as a watercourse, but as a place of silent resistance, of tenacious passions, and of bonds that defy time. The radio documentary reveals an unexpected world, reminding us that, even in a distracted age, the river continues to carry with it the stories of those who have chosen to listen to it. A documentary by Andrea Falzone and Claudio Sponta. The audio documentary was produced as part of the "Audiovisual Reportage" course at the Abruzzo branch of the Centro Sperimentale di Cinematografia and broadcast on Tre soldi, a program on Rai Radio 3.
