Two teenage girls who are best friends experience a falling out over a boy. One of the girls is murdered, but returns three months later unchanged. The surviving friend seeks revenge for her friend's death. Scenes would include the school covered in missing posters, stalking of the popular girl, and her murder. Comparable films include Jennifer's Body about a demonically possessed girl who kills classmates, and Scream about a group of teens terrorized by a killer using horror films as part of a deadly game. Shots like those from inside closets or lockers would build suspense, and tracking shots could show a character being followed. Costumes would distinguish the popular and nerdy best friends.
