Mara Ellison, a quiet museum archivist, uncovers a forgotten set of letters that lead her to the Hall, a hidden building that draws people together while slowly taking pieces of them away. As she connects past disappearances with present experiences, Mara joins others who have been affected, choosing collective memory and openness over silence and isolation. Together, they bring the truth back into the light, proving that ordinary people can interrupt repeating shadows simply by refusing to forget.
