But when Amos is brutally murdered during a livestream and Odette is filmed covered in his blood, there's no question who's to blame.

The video of the murder quickly goes viral, and the world is hungry for answers. How did a sweet, lonely girl turn on her only friend? And why won't she say a word in her defence?
