"The High School Reunion, Part 2: The Gang's Revenge" is the thirteenth and final episode of the seventh season of It's Always Sunny in Philadelphia.
Dennis and Dee sit at a table at their reunion, alone and sad of the events that just occurred. Dee tries to mock Ingrid Nelson to be cool again, but because Ingrid isn't fat anymore it doesn't work. Dennis hatches a plan: to bang Tim Murphy's black wife. He approaches Christie and tries to flirt with her but she tells him that she thought he was gay, and that she never wants to sleep with him.
Dee sets off to find Charlie, Mac, and Frank who are hanging by their underwear in the bathroom. She offers to help them get revenge but when their best plan is to get the "Freight Train" gang from school together she bails and leaves them hanging. They manage to get down and eventually Dee asks to join the Freight Train. To initiate her, the three give her a massive wedgie.
Out in the parking lot, Dee has put back on the scoliosis suit she had to wear in high school because the wedgie hurt her. An enraged Dennis heads to his Land Rover where he reveals a hidden compartment with tools he says he uses for his fetish: zip ties, duct tape, a video camera, and rubber gloves. The rest of the gang stops him and recruits him to the Freight Train. Inside the school, they stop the cool kids and Dennis calls Tim Murphy out to fight. Dennis yells about Adriano being jealous and turning the students against him but Adriano breaks it down that Dennis was never the popular figure he thought he was as he would yell about everyone being minions but then just hang out with Charlie and Mac. Tim reveals that it was Mac who slept with Dennis' prom date, not him. Dennis turns his anger toward Mac while the cool kids walk away. Frank manages to inspire them all, and Charlie suggests they try "Plan B".
"Plan B" is a musical dance number. The gang clears the dance floor and Charlie gives a speech on how dancing is saving high school students nowadays. The begin dancing to George Michael's "Freedom! '90". The crowd, including the cool kids, cheers and responds very well to the well choreographed and well performed show. Suddenly, reality snaps into place and it turns out the gang has no rhythm or dance talent and are just sweatily flailing around on stage. The song ends, Frank vomits, and Adraino invites everybody but the gang to his house for an after-party.
As they leave the high school (in denial over how bad the dance number was), a very drunk waitress offers to bang the next person to talk to her. Schmitty swoops in to surprise the gang and talks to her. They leave together.
