Ilja Richter, showmaster of the cult programme Disco on ZDF until 1982, was considered the darling of the nation. During his television career, no one suspected that Ilja was the son of a persecuted communist resistance fighter who survived years of imprisonment in concentration camps: Georg Richter. The film accompanies Ilja Richter on his search for clues. The story of his father as a concentration camp inmate is revealed in fragments and is representative of the story of many prisoners.
