Non-english movie, european.. probably russian. I think the first scene was when the lead female (teen) was using her laptop in her room, then she went to school and the teacher asked them to show their homework(?) which was supposed to be like an invention for science class idk, then the girl showed her work which was like a voodoo doll, and she was kinda proud of it. The girl is pretty but she is like a weirdo/psychopath/mentally illed.
