Guillermo Aguirre

The story of the friendship between a truck driver and a shoeshine boy who occasionally becomes his assistant when they travel together from the agro-industrial area of Santa Cruz to the high Andean basin of La Paz in a truck named "Mi Socio".

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).
