A unique look at the life of celebrated American author Patricia Highsmith based on her diaries and notebooks and the intimate reflections of her lovers, friends and family. Focusing on Highsmith's quest for love and her troubled identity, this documentary sheds new light on her life and writing. Highsmith herself was forced to lead a double life and had to hide her vibrant love affairs from her family and the public. Only in her unpublished writings (voiced by Gwendoline Christie) did she reflect on her private life.
