Sixteen-year-old Anna is an unremarkable schoolgirl. She does her homework, and keeps out of trouble. At home she emotionally supports her depressive mother and occasionally goes out with friends, but she allows no one to get close.

But there's something he's not telling her. They set up the job to steal from Ritchie’s dad’s house, but when his father discovers them, it transpires that Ritchie is really there for a completely different reason — to kill him. And to Anna's horror, he pulls out a gun …
