In 1922 in Cornwall, a prodigious young pianist and composer Olwen Trevelyan Audrey Fildes is struggling with the ending of a piano tone poem she is composing. Driven to complete the piece by her domineering elder sister Julia Sonia Dresdel, Olwen becomes agitated and despondent, and one night sleepwalks to the edge of a cliff near their home. Julia follows her and shouts her name but Olwen, abruptly awakened, loses her balance and falls to her death on the rocks below. Julia is unable to come to terms with Olwens death and the guilt of her own role in it, over the years becoming a reclusive, obsessive figure whose main raison detre is to keep Olwens memory alive. Olwens final composition gains her posthumous recognition, and each year on the anniversary of her death it is broadcast on the radio. On the 25th anniversary of Olwens death, Julia is listening to the broadcast when she hears a frantic knocking at the door and opens it to admit an unknown young woman Carol Raye, who immediately walks up to the piano and begins expertly playing along with the piece on the radio. The young woman claims to have lost her memory and to have no idea of who she is or how she came to chance upon the isolated house, yet she seems to have a familiarity with the surroundings and the history of the Trevelyan family. Struck by her physical resemblance to Olwen, Julia offers her refuge and, also seeing behavioural traits reminiscent of Olwen, becomes convinced that the woman is the reincarnation of her dead sister. A local faith healer Nehemiah Tom Walls, who also claims second sight, becomes involved and it seems increasingly as though history is repeating itself, culminating when the young woman too is found standing precariously on the edge of the cliff from which Olwen fell.
