Finding herself suddenly alone after nursing her demanding mother for many years, Caroline suffers a breakdown. With the help of Jon, a gentle man with a breakdown in his own past, she gradually reinvents herself as Charley, a bright, independent woman. She and Jon travel to Tunisia where, in a cool, light villa by the sea, Charley’s true healing begins and she and Jon discover a warmth that brings them closer together. But then shadows begin to close in on them again, tarnishing the beauty of their new-found love. Their Tunisian hostess becomes ill, her adopted child disappears, and a sinister stranger is discovered haunting the villa. It will take all of their strength and love to bring back the light they had found.
