Butters shows up at lunch with a black eye, saying that a bully has taken his money for the third day in a row. Despite the boys encouragement, Butters decides he doesn't want to tell or rat the bully out. Stan, on the other hand, insists that they shouldn't just stand by and do nothing. Kyle suggests maybe he talk to his grandma, who's in town visiting.
Butters goes to talk with his grandma, but she starts slapping him, calling him a bitch and trying to take his lunch money. Turns out the grandma is the one bullying .
Back at school, Mr. Mackey is visited by the spokesman for Bully Buckers -- a company that gives anti-bullying assembly to the kids about the dangers of bullying. After relentless pressure and harassment from Bucky Baily, Mr Mackey gives in and agrees to the assembly.
In the hallway, Red tells Butters that his grandma is looking for him. Terrified, he runs to hide in the bathroom…but she's there, waiting. She's heard about the anti-bullying counselor and tries to make Butters eat a "NARC puck" for tattling on her. Just in time, Mr. Adler knocks on the door and escorts her to the womens room.
At the bullying assembly, Bucky Baily tells the kids that the only way to stop bullying is if everyone is united against it. Stan volunteers to make a
He then asks for one student to come forward and be the leader of the anti-bullying campaign, and direct an educational video. After pressuring the students, Stan volunteers.
Stan's cheesy video, "Stop Bullying", starts with the kids bullying and then jams into a music video that goes through the entire South Park Elementary. And features all the kids in one, big long shot. But when it comes to Butters solo, he says he doesn't want to do it, and that the video would only make things worse for him.
Fed up, Kyle confronts Stan about his true motives, which Stan says is awareness. Kyle argues that it's less about awareness than it is about Stan, and warns him to careful that he doesn't wind up naked and jacking it in San Diego.
Meanwhile, back at Butters' house, Grandma continues to bully Butters, unbeknownst to his parents. Stan, Cartman and Kenny stop by with good news -- a movie company bought the anti-bullying video, and the movie company wants to do a potshot with him so they can make movie posters! This of course pisses his grandma off.
Back at school, the kids cheer for Stan. But Buckey Baily is waiting for him in the bathroom to confront him, saying he had no right to sell the movie and that it's property of Buckey Bailey Bully Buckers.
Back in Butters' room, with no other options, he turns to his darker side -- Professor Chaos. But when he goes in to confront his grandma, he is met with an even more horrific sight. His grandmother in very revealing villain costume. When Butters refuses to fight, is forced to endure "GUMMY BEARS".
After enduring this, Stan takes Butter's onto the Doctor Oz show, and after Doctor Oz asks two questions to Butters, he goes berserk, attacking Doctor Oz and making Stan's video seem misleading because Butters is a "crazy psychopath". Stan then walks into school and is booed by everyone. He discovers that because of Butters' meltdown, he got the school a lawsuit and made it look stupid. Afterwards, Stan goes to San Diego, and as Kyle predicted, jacks it.
