Well, as a summary, it's about a facebook stalker girl who liked a guitarist. So she decided to take the place of his nun teacher by killing her and teaching him instead. We then see that she tempted him to realize then that it was wrong. He later wanted with his sister to discover who she really is,for that they, and so ridiculously used her openned laptop to see her real name. Then the guitarist killed her with a screwdriver... super lame and boring tbh
