It is a fateful moment: during one of his concerts, Jewish pianist Klaus Seiser discovers Gestapo officer Dr. Becker in the audience. He had imprisoned and harassed the young Seiser in 1943 because of a leaflet. Although the musician had managed to escape from prison at the time, he was caught at the Swiss border and Becker had him sent to Dachau concentration camp. Now, years after the end of the Nazi regime, Seiser denounces the Gestapo man and hopes for justice.
