In the harsh winds of 1840s England, acclaimed but overlooked fossil hunter Mary Anning toils along the Lyme Regis coast, her discoveries unrecognised by the male-dominated scientific world. When a wealthy visitor entrusts his fragile young wife, Charlotte, to Mary’s care, an unexpected intimacy blossoms between the two women. Against the backdrop of isolation and societal constraint, Ammonite unfolds as a tender, restrained love story — a portrait of longing, resilience, and the quiet defiance of those who live beyond convention.
