More brainstorming on Final Idea

I'm deciding in leaning my final project towards a teenager's self-struggle between the past and the present. My main character, named Elizabeth, was kidnapped a few years ago by two females. This experience changed her life as she became anti-social and scared of even living. After my opening scene, Elizabeth will have a slight change in her personality and will become her one secret agent to be able to get revenge on those who kidnapped and hurt her.
