Before I Fall asleep

Every Day for Kristen (Nicole Kidman) It's a completely new day for Christine. A terrible car accident 20 years ago fixed her memory on that day. Severe brain damage left her with only 24 hours of memory. For Christine, every day, she wakes up in a strange bed with a strange man lying next to her, and this strange man is her husband Ben (Colin Firth). Every day, Kristen would have a phone call with Nash (Mark Strong), the doctor in charge of treating her. With the help of Dr. Nash, Kristen gradually pieced together her own history. It turned out that at the end of each day, Kristen would write down what happened on that day in her diary. But gradually, Kristen discovered that what was recorded in the diary was very different from what Ben told herself. One day, when Christine opened the diary again, she found a sentence written in the diary: Don't believe Ben.
