For three years, Song Yan has filled the emptiness of her Beijing apartment with the tentative notes of her young piano students. She gave up on her own career as a concert pianist many years ago, but her husband Bowen, an executive at a car company, has long rebuffed her pleas to have a child. He resists even when his mother arrives from the southwestern Chinese region of Yunnan and begins her own campaign for a grandchild. As tension in the household rises, it becomes harder for Song Yan to keep her usual placid demeanor, especially since she is troubled by dreams of a doorless room she can’t escape, populated only by a strange orange mushroom.
When a parcel of mushrooms native to her mother-in-law’s province is delivered seemingly by mistake, Song Yan sees an opportunity to bond with her, and as the packages continue to arrive every week, the women stir-fry and grill the mushrooms, adding them to soups and noodles. When a letter arrives in the mail from the sender of the mushrooms, Song Yan’s world begins to tilt further into the surreal. Summoned to an uncanny, seemingly ageless house hidden in a hutong that sits in the middle of the congested city, she finds Bai Yu, a once world-famous pianist who disappeared ten years ago.
