Black Out

All her life Marie would black out for minuets at a time. While she was out she would do things she was completely unaware of. She never has any recollection of it when she finally comes to and she can never control what she does. One rainy night, things get out of hand. She wakes up only to find a dead man. No witnesses to clear her name, but the evidence only points to her. She held the knife, the blood was on her hands. Her friend frantically tries to help clear her name and prove her innocence even though she's convinced she murdered him and other people. Is this the beginning of a violent murdering spree or is it all just a big mixup?
