These Shining Lives is a play based on the true story of the Radium Girls, young female factory workers in the 1920s and 30s who painted clock and watch dials with radium-based luminous paint. The synopsis details how these women, unaware of the dangers, were encouraged to use the "lip, dip, paint" method to create fine points on their brushes, leading to devastating radiation poisoning. The play follows their fight for justice and accountability against the company that hid the truth, ultimately highlighting themes of friendship, survival, and the fight for labor rights and workplace safety.
