Sarah is found unconscious on the road leading into Antiquonia by Karim, the town's ambulance driver and an enthusiastic lover of a good mystery. He reports the case to Julia, the police officer, who takes a personal interest even though her supervisor has no enthusiasm for the matter. As Sarah recovers, she meets the town's inhabitants one by one — a former bar owner now tending the convent garden, a nun with more history than she shares, and others — each carrying their own story and their own reasons to be cautious around strangers. Eventually, the puzzle of Sarah's own past begins to surface, and the real challenge of understanding who she is and what brought her to this road begins.
