Sarah has no memories. She just knows she was found, near death, on a beach miles from her London home. Now she is part of a medical experiment to see whether her past can be retrieved. But bad things seem to have happened before she disappeared. The police are interested in her hidden memories too. A kind man she meets by chance seems to have her best interests at heart, seems to understand her, almost as if he knows her... As she fights to regain her memories and her sense of self, it is clear that people are hiding things from her. Who are they protecting? Does Sarah really want the truth?
