Ghost music

When Song Yan's mother-in-law moves into the apartment she shares with her new husband Bowen, their carefully calibrated life is overturned. Family secrets are uncovered - a disappeared sister, a former wife; family plans are put on hold - can they possibly try for a child in these circumstances? Trapped and disorientated, Song Yan begins to question whether she knows anything at all about the man she chose to marry. He, in turn, withdraws from her completely. When mysterious parcels of mushrooms begin to arrive on the doorstep, purporting to arrive from a virtuoso pianist, Bai Yu, whom everyone had believed to be dead, Song Yan seizes on the invitation to track him down.
