The plot deals with the developments in an old decadent village after a stranger arrives at the old train station, an event in itself. This stranger is a Brazilian musician who carries and plays his "oboe". The music from the oboe, the musician's instrument, will change the lives of everyone involved, and that small village itself will forever be changed by the sound of the oboe.

After the end of the military dictatorship in Argentina in 1983, Floreal is released from prison. Instead of returning to his wife, he wanders through the night of Buenos Aires. He meets some people from his past–most of which are only imaginary–and remembers the events of his imprisonment.
