The Day Silence Died (1999)

Original title: El día que murió el Silencio

A handsome and mysterious stranger, played by Darío Grandinetti, walks into the town square of Villaserena one day and strategically places loudspeakers around the town, blaring a variety of musical tunes. Soon, he begins to sell airtime to the various locals, who broadcast their own personal love dedications and (more frequently) insults for all to hear. A subplot evolves between Abelardo (the stranger), Celeste (a young woman who is chained inside her father's house to stop her running away), and José (a young man).
