Ria and her little brother are hiding from their psychotic father, who's out to kill them. To support herself and Levi, she gets into underground fighting, and is really good at it. They start going to school, and she meets friends who help her more than she could imagine. Then a man comes along and tells her and Levi to go with him, so he could protect her. Ria thought this was all ridiculous, that her father would never find them. But on her prom night, everything she's ever known goes terribly wrong.
