Bloody amnesia

So the title might be changed, but haven't decided yet. It's about an amnesiac (cliche yeah, but oh well), named Alice who lives a peaceful life surrounded by those who care about her. Her life gets turned upside down when a friend is murdered. At the scene of the crime is a symbol; a symbol that seems to connect to Alice's past. Now in a race against time, she has to unlock the secrets of her past in order to save the lives of everyone she cares about. But what she discovers might just be her downfall.
