Mauricio is serving time for his political ideals in Barcelona in the 1950s. The only contact he maintains with the outside world are the letters he writes to his partner Helena. These letters are written on the skin of fellow prisoners who are released. One day the messenger who leaves prison has nothing written on his skin. That is the day of Mauricio's execution.
