Christine Lucas wakes up every day next to a man she cannot recognize. He calms her down and tells her that she is his wife and that she is currently 47 years old. Two years ago, he explains, she met with a terrible accident which resulted in her current affliction: anterograde amnesia. She can’t form new memories. Alarmed at her discovery, she struggles to come to terms. After the man leaves for work, she receives a mysterious phone call from a doctor claiming to be her physician. His name is Dr. Nash and he has been treating her without the knowledge of her husband. He guides her to a journal she had been maintaining. The contents of the journal shock her. The first thing she needs to remember is that she can trust no one, especially not her husband.
