Clara Immerwahr – a scientist who was the first woman in Germany to receive a doctorate in chemistry. However, pressure to adhere to traditional gender roles and the outbreak of World War I did not allow her to fully develop her potential.

Together with her husband Fritz Haber, who won the Nobel Prize in 1918, she worked on the abstraction of ammonia. Unlike another scientific couple – Marie Curie Skłodowska and Pierre Curie – Clara and Fritz's cooperation and coexistence gradually became problematic. The main themes of the TV movie include not only the position of women in science and society, but also the use of scientific research for war purposes. Indeed, Haber is called the father of chemical warfare, which Clara publicly disagreed with.
