Prague, August 10, 1942. Hans Krasa, a Czech composer and orchestra conductor of Jewish origin, is arrested by the SS and sent to the concentration camp at Theresienstadt. A good number of other musicians, composers, and singers have been imprisoned with hi. Adolf Eichmann wants to turn Theresienstadt into a model camp, to show the world that Jews are not only exterminated but that they are also permitted to maintain an intense culture life, composing and interpreting music at the highest level. Hans, who is under no illusions about the fate that awaits them, accepts the diabolical game proposed by the Nazis. His goal is to live. In addition to the musicians, the novel has another protagonist, Elisabeth von Leuenberg, who comes from an aristocratic background and is one of the most prominent scientists in Nazi Germany. All of these characters are used by Xavier Güell to create a beautiful homage to music.
