In 19th century England, the life of Mary Anning, a self-taught paleontologist, unfolds in a small coastal town of Lyme Regis. Known for her fossil discoveries, Mary lives a solitary and austere existence, marked by loss and struggle in a male-dominated field. Everything changes when a young woman, Charlotte Murchison, arrives in Lyme with her husband, who seeks out Mary to show him the secrets of paleontology.
After a series of awkward encounters, the bond between Mary and Charlotte begins to deepen as they share their respective孤独. Charlotte, trapped in a loveless marriage and coping with the grief of her child's death, finds in Mary not only a mentor but also an emotional connection that challenges the social conventions of the time.
As the waves crash against the shore and days pass, the two women delve into a world of discovery, both in terms of fossils and their own identities. Through moments of tenderness and vulnerability, Mary and Charlotte establish a passionate relationship, but reality and external pressures threaten their happiness. This love story and struggle in a time and place that often rendered women invisible becomes a poetic and heart-wrenching portrait of longing and aspirations, where the search for truth and love intertwines in the sand and rock.
