1914 marks the genesis of a silversmith's finest work, a singing filigree bird within a music box, a token of love for his son, before the shadow of World War II falls over his Jewish family. Decades later, the box emerges as a beacon of revelation for Londoner Lilian Morrison, thrusting her into the depths of her unknown origins as a Holocaust survivor. This multigenerational epic follows Lilian's journey to uncover her heritage and the fate of her scattered family, all divergent paths woven by a shared thread of sacrifice, identity, and reconciliation, a journey echoing with the haunting melody of survival and the steadfast dream of a united future.
