In Tenby, a popular holiday resort in Wales, freelance journalist Sarah Brighton investigates the discovery of the skeleton of a young woman whose death dates back forty years. With the help of Nora Taylor, owner of a nostalgic local hotel, and the fisherman Marcus Davon, the journalist tries to reconstruct the main events of the time, focusing on a mysterious plane crash in which pilot Harry Holton lost his life in the late 1950s.
