(Full Synopsis)

Set in the late 19th to early 20th century, the musical unfolds in Paris, where Marie Curie confronts the consequences of her groundbreaking discovery of radium.

As she reflects on her life near its end, Marie recounts her journey from Poland to France, where she pursued scientific study at the Sorbonne and formed a close friendship with fellow immigrant Anne. Despite discrimination as a foreign woman, she perseveres in her studies and research.

Together with Pierre Curie, she discovers radium and gains international recognition through the Nobel Prize. Anne, introduced to work at a radium factory through Marie, initially achieves stability, but soon becomes aware of a series of unexplained worker deaths.

Investigating further, Anne uncovers evidence that the company has concealed the harmful effects of radium. As she attempts to reveal the truth, Marie is forced to confront the dual nature of her discovery—its potential to heal and its capacity to harm.

Faced with conflicting responsibilities as a scientist and as a human being, Marie must ultimately decide how to respond to the consequences of her work.
