Christine wakes up next to a man she does not recognise. Panic stricken, he slowly explains that he is her husband, and that she suffered a terrible accident that has given her amnesia. Every morning, Christine wakes up a stranger, and every night her memories fade into nothing. With the help of Dr Nasch, Christine is trying to regain her memory. That is, until one day, when new terrifying truths emerge that force her to question everyone around her, and what really happened to her on the day of her 'accident'.
