On the cold winter afternoon, Sunset Shimmer is laying in her room, crying. She was falsely accused by her friends, well former friends for being Anon-a-Miss.
It was all started one week ago, She and Applejack arrived to school. Sunset wasn't excited because she hasn't been home for the holidays for some time and has never been close to anyone, not even her own family. She assures Applejack she's okay because she has her and the other girls now, and she departs for class. Applejack takes out her cell phone and texts the rest of her friends to meet her in the library after school.
Later that day, Cheerilee catches Pinkie Pie using a school computer to go on the social networking website MyStable. The other girls join her, and Applejack shares her plan to help with Sunset's holiday loneliness: consecutive slumber parties at each of their houses. The others agree to the plan and Pinkie goes to tell Sunset.
The first slumber party is held at Pinkie Pie's house. During the merriment, Applejack gets a call from Apple Bloom, who wants to make sure her big sister is doing okay. Applejack tells her she's fine, and Apple Bloom closes the call by calling Applejack "Piggly Wiggly." An embarrassed Applejack explains that, when she was a baby, she played with the pigs in the pigpen and earned the nickname from Granny Smith.
That night, after everyone else has gone to sleep, Sunset Shimmer writes to Twilight Sparkle in her magic journal.
The next morning at school, Applejack hears someone call out the name Piggly Wiggly. As she wonders who it was, Apple Bloom runs up and tells Applejack that someone with the username "Anon-a-Miss" posted Applejack's story to MyStable. Applejack overhears several students gossiping about her, but she doesn't let a little teasing bother her. As she and her friends wonder about the identity of "Anon-a-Miss", the school bell rings and they head to class.
Realizing that no one outside Applejack's circle of friends know about her nickname, Apple Bloom suggests that "Anon-a-Miss" is Sunset Shimmer, but Applejack refuses to believe such a notion.
After school, Rarity picks up Applejack on the way to the second slumber party at Rarity's house. They meet up with their friends there, and Rarity dismisses Sweetie Belle from the party, much to Sweetie Belle's dismay. As the slumber party gets underway, Sunset Shimmer takes photos and video with her cell phone. During an ill-planned stage dive, Pinkie Pie discovers Rarity's "closet of shame", where Rarity keeps her awful outfits. The six friends use the outfits to play dress-up, and Sunset takes more pictures.
That night, Sunset writes to Twilight again, expressing how loved and accepted she now feels, before going to bed.
Later that week, Sunset meets her friends in the school hall, and they confront her; all the pictures Sunset took at the slumber party have been posted on "Anon-a-Miss"'s MyStable page. Thus, the five friends conclude that she is "Anon-a-Miss". Sunset pleads innocence, but due to the evidence against her, the other five don't believe her. They denounce Sunset as their friend and walk away, and Sunset breaks down in tears.
Days pass, and as "Anon-a-Miss" posts more and more of the girls' humiliating secrets to MyStable (like Rainbow Dash's poorly graded research paper), they become laughing stocks at Canterlot High. Sunset Shimmer confronts Trixie in the hallway, and although Trixie denies being "Anon-a-Miss", she praises her for her actions. In the cafeteria, an angry Rainbow Dash sits next to Fluttershy. They notice that "Anon-a-Miss" has started posting about everyone at the school, turning everyone against each other. They don't want to believe that Sunset Shimmer is "Anon-a-Miss", but there are no other possible suspects.
Sunset was crying in her apartment, she saw Applejack and Rarity walking by her house and beaten her up. Fluttershy, Pinkie Pie and Rainbow Dash watches as they unfriended her on other social media and take back the gifts they got for her, leaving Sunset in tears.
And that was it, Sunset arrived to the store the next day and buy a rope. When she bought it, she ties it the end to the ceiling. She's about to hang herself and...
She's gone.
The CMC arrived to tell Sunset that they're Anon-a-Miss, but it was too late. Sunset hung herself. Scootaloo call the ambulance as Sweetie Belle and Apple Bloom tells their sisters that they are Anon-a-Miss, but they never believed them and plans to get revenge on Sunset.
In the next day of school, the Main 5 and all the classmates are preparing to teach Sunset a lesson by throwing rotten apples at her, the police announces that Sunset Shimmer has died last night. Apple Bloom, Scootaloo and Sweetie-Belle revealed to the entire school that they are Anon-a-Miss and feels responsible for Sunset's suicide.
At Sunset's funeral, Applejack, Rarity, Rainbow Dash, Pinkie Pie and Fluttershy are feeling guilty for what they've done to her.
"It's all our fault, we should've believe her that she wasn't her." Fluttershy said in tears.
"I can't believe it. What kind of friends are we?" Rarity asked.
"Rest in peace, Sunset Shimmer. Rest in peace. "Applejack said in tears. "Come on, y'all, let's go home."
As everyone are headed back home, two mysterious men appeared beyond the tree, one of them holds up a plastic bag with Sunset Shimmer's hair in it. The other men holds up his phone and start calling.
"Mission accomplished, boss. We got her hair." One of the men said.
