Biopic of the famed scientist and the work she did with her husband Pierre (Walter Pidgeon) in the discovery of radium. Marie (Greer Garson) was a student at the Sorbonne studying for her Master's degree in physics when they first met. She received permission to use space in Professor Pierre Curie's laboratory. They soon fall in love and are married, working together on trying to isolate a radioactive substance Marie has identified as radium. Years of painstaking research and experimentation led to success and Marie and Pierre Curie shared the Nobel Prize in Physics. Sadly, Pierre was killed crossing the street in the rain when he was run over by a horse and wagon. Marie continued to work and make major contributions to science.
