After discovering that she has only a short time left to live, concert pianist Lissa travels to Cornwall for the final fling of her life. While there, she falls in love with young mineral prospector Kit, a man whose dark secret prevents him from fighting in the War. Unbeknownst to Lissa, however, Kit's affections are also much in demand from a rival of hers.

In 1922, young pianist and composer Olwen Trevelyan, troubled and sleepless over her inability to finish the final notes of her composition, falls to her death from the cliffs of Cornwall. 25 years on, Olwen has gained posthumous fame as a result of her tragic death and her haunting uncompleted composition 'The Dream of Olwen'. Her reclusive sister Julia (Sonia Dresdel), who has never come to terms with Olwen's death, becomes convinced that Olwen has returned when she meets an amnesiac woman who looks like her.
