Winter break is over. She is already serving time in detention and feeling sorry for herself, when she notices that someone from her past is back in her life.
During lunch period, she sits and stares at Jessica and wonders about why she is back and why hasn't she come talk to her. She notices a post-it left on her diary.
Another day, another detention hour. But as she leaves school, she notices a guy in the library photocopying a book with a very intriguing title. She googles it to figure out what it could be all about.
She plays with the cutest German shepherd on her way back from school. This memory is strangely stored in her mind. The puppy feels sick, and some guys from school approach her outside her house.
She has her first face to face with Jessica, since she returned. The owner of the dog informs her she will be moving away. Someone at school got in a fight.
She notices some activity at school where money is being passed down from classmate to classmate. Jessica distracts her to talk about Mr. Morgan's video.
Turns out Jessica wasn't talking about Mr. Morgan's first video, there was a second video. One where he is angry; at his followers, but especially at her. She gets the dog passed on to her as her neighbor moves away.
She takes Jessica to an interview with a guy that they think will help them solve the mystery of the book and the money being passed around in school. She remembers what it's like to have Jessica as a friend again.
Everybody at school is trying to find out who is part of the mob of students that attacked the school. She hears from Jessica that Bobby wants to ask her to be his prom date.
She spends the day with Jessica, but ends up seeing something that makes her doubt if Jessica is with her to be her friend again or for something else.
Someone stalks her from the sidewalk outside her house, through the window. She holds her German shepherd to protect herself and tries to find out who that might be.
She starts recounting how many people she needs to be on the look out for in order to feel safe. But coming out from the movie theater, she notices someone follows her out.
She is out walking with Jessica at a park, when all of a sudden, Jessica falls to the ground. Rocco reveals himself and Bobby appears on the opposite side. An epic battle is about to unleash.
