Les trottoirs de Saturne

Fabián Cortés (Rodolfo Mederos) is a bandoneonist from Aquilea, a country living under a military dictatorship. He's exiled and lives in France, where he's a well-known musician. Nevertheless, he wishes to return to his country. His sister Marta, a left-wing militant, travels to France with her comrades to bring him back to Aquilea.
