Female prisoners in a Nazi concentration camp (Auschwitz) are spared from death in return for performing music for their captors.

In World War II, the Jewish French musician and cabaret singer Fania Fenelon Goldstein is sent by the Nazis from Paris to the Auschwitz Concentration Camp. The guards take her clothing and luggage and they cut her hair very short. One day, when she is very weak, she hears someone asking whether any prisoner could sing Giacomo Puccini's Madama Butterfly and she joins the group of musicians that have been spared from the gas chambers to entertain the Nazis performing music for them. She convinces the conductor Alma Rose to invite her friend Marianne, telling that she would be a talented singer. Along the years of abusive treatment, they survive but losing their dignity.—Claudio Carvalho, Rio de Janeiro, Brazil

Fania Fenelon, a classical pianist and singer in Paris, is arrested during the Nazi occupation for her support of the French underground resistance. After being sent to the Auschwitz concentration camp, she is recognized as a famous musician, and becomes a member of the camp's all-female orchestra. Although the group, under the leadership of conductor Alma Rose, forms a close bond, the strain of performing for their tormentors grows.—Jwelch5742
