A jaded psychotherapist returns to her first passion of becoming a writer. However, her life is complicated by a desperate film actress who wants her help, and who draws her into a world of questionable ethics.

A sly, sultry character study from filmmaker Justine Triet, SIBYL follows a psychotherapist (Virginie Efira) who decides to quit her practice and return to writing instead. As Sibyl starts dropping patients, she begins to struggle with excess time and a lack of inspiration--until she gets a call from Margot (Adèle Exarchopoulos), a young actress wrapped up in a dramatic affair with her costar, Igor (Gaspard Ulliel), who happens to be married to the film's director (Sandra Hüller). Becoming further enmeshed in Margot's life, Sibyl starts to blur past and present, fiction with reality, and the personal with the professional as she begins to use Margot's life as source material for her novel.—Music Box Films

Fascinated almost to the point of obsession, Sibyl becomes more and more involved in Margot's tumultuous life, reviving volatile memories that bring her face to face with her past.
