Ghost Music weaves a tale of a life interrupted. Former concert pianist Song Yan, who relinquished her dreams to the dim glow of her students' music, is drowning in the mundanity of life in her Beijing apartment. Her husband's reluctance to welcome a child into their lives only furthers her isolation—until an unexpected arrival from her mother-in-law opens doors to long-buried family secrets. Curious parcels of mushrooms lead Song Yan on a path toward the surreal, stirring within her troubling dreams and an insatiable quest for connection. In this search, she encounters the enigmatic Bai Yu, a pianist thought lost to time, tucked away in the depths of the city. This atmospheric journey carries Song Yan through a labyrinth of music, memory, and self-discovery, against the canvas of a transforming Beijing. It's a symphony of personal evolution and the courage to embrace new beginnings.
