Gail May, a trainee therapist, is seeing her first patient, that all-important person on whose case study her qualification depends. As a trainee, Gail is careful to adhere to all the therapeutic rules. What she finds most difficult is that for a long time her patient, an Eastern European woman who believes she is being stalked, hardly ever speaks. Feeling starved of information, Gail begins to resort to increasingly unorthodox means. With Gail's private life falling apart her interest in her patient intensifies, growing into an obsession. When the lines between fiction and reality, between intrusion and therapy, become dangerously confused, Gail will have to face the consequences of her actions.
