Eva (14) is already an orphan when she arrives in the Auschwitz concentration camp. She hopes to find her friends there from the Theresienstadt camp children's choir, who were deported before she was. She had accompanied the choir on the piano. Miraculously, she finds Renata, but the former soprano appears to have given up on life. Eva tries with all her might to keep Renata alive. It is her music that gives Eva the strength to keep going, because only that will make it possible for the two girls to escape the hell in which they find themselves.
