Two women are in a laboratory many years ago. They are measuring substances and conducting experiments together. However, they are unlike other women of their time. Instead of being home, with their families where society believed they belonged, they were doing what they loved - science. They were trying to discover more information about radioactive substances through various experiments. They work for many weeks on this project and eventually draw conclusions that are novel and new for the time. However, instead of being recognized for their accomplishments, the men in the laboratory take the credit for the work and their work goes unnoticed. However, many years later, they are finally recognized for their accomplishments in the field of chemistry.
