Un cop acabada la guerra civil, l'anarquista Francesc Sabaté continua fent incursions a Espanya des de França per tal d'enderrocar el règim franquista. Tot i que han mort gairebé tots els seus companys de lluita, i també els seus germans, decideix baixar a Barcelona a peu juntament amb quatre guerrillers més. Un cop a Catalunya, no tarda a veure que les coses han canviat, que la gent no està disposada a ajudar-lo com sempre i que la policia va un pas endavant.

Sabaté lives in exile in France, but since the end of the Spanish Civil War he has never stopped making forays into Spain in an attempt to overthrow fascism in the only way he knows and considers effective: direct action. This journey, structured like a road-movie with a hint of western, highlights the fears of four characters and Sabaté, their past, their regrets and questions about their cause and the violence, uncovering the ghosts of the past of all these characters in a fast-paced adventure where both sides show that they are fine adversaries.
