1953. Mei's 'gift' of speaking to ghosts is one that she has endeavoured to bury while fighting to survive as a refugee in post-war, post-revolution Hong Kong. When former silent film star Holly Zhang invites Mei to the infamous Maidenhair House, the startling summons revives her link to the man who destroyed her life. During six séances over six nights, each night a medium will be asked to leave until only one remains as the recipient of a staggering reward, but the only prize Mei wants is revenge. Years later, that shocking night in the labyrinthine mansion has become an urban legend, dismissed by the police at the time as a collective hallucination. Mei must uncover the truth of what really happened and see if the ghosts she has carried can finally be laid to rest.
