|On their way to class, the study group become dejected when they see other students happily enjoying the course they originally signed up for, "The History of Ice Cream". Jeff tries to reassure everyone about their new history course but is taken aback when he sees that two of the Germans he and Shirley faced off against last semester are taking the class as well. The third member introduces himself to Jeff as Reinhold, the brother of the other German he had met named Juergen. The tense situation is interrupted by the arrival of History teacher, Professor Cornwallis. The professor briefly introduces himself to the class and announces their first assignment. He asks the students to imagine how history would be written if the losers of a conflict had been the winners.
|Meanwhile, Dean Pelton enters his office and is shocked to see Ben Chang sitting at his desk. Also in the room is a Dr. Ken Kedan from Greendale mental health services who tells him about "Kevin"'s "Changnesia". After learning about Chang's connection to the school he decided it best to have his rehabilitation here. Pelton refuses but is told that it had already been cleared through the school board. At the same time, the study group arrives at Group Study Room F and find The Germans inside. Jeff insists they leave but Annie suggests they let them stay since they are only occupying a small corner of the room. The Germans quickly accept the invitation before any other protests could be made with Karl making a pithy comment that Abed recognizes. He later confronts the German student at his locker and they bond after Abed explains they are both players of the same MMORPG.
|Back at Dean Pelton's office, Carl Bladt and Richie Countee explain to Pelton that the school is being paid to help Chang in his recovery hence their willingness to allow him back on campus. Meanwhile, the study group finds the Germans in the study room again except this time they are seated at the study table. They insist the trio leave causing Reinhold to call security who tells the study group to go as the Germans had reserved the room. The next morning, the study group arrives early at the administrations office to sign up for the study room but are beaten there by the Germans. The group is forced to hold their study session in a rundown basement. After a faulty light bulb nearly electrocutes Pierce, Jeff resolves to have everyone get up earlier to reserve Group Study Room F. Unfortunately their next few attempts prove just as unsuccessful.
|Meanwhile, Pelton is annoyed by what he perceives as Chang's innocent act and fills the amnesiac in on what he did last year. After learning he staged a coup at Greendale, held the dean hostage for months and almost blew up the school Chang/Kevin runs out of the office horrified. Over in History class, Professor Cornwallis finishes up his lecture and the Germans taunt the study group about having taken over their study room. Angered, Jeff then convinces the rest of the group to take drastic measures to defeat the Germans. As part of the plan, the group throws a lavish Oktoberfest celebration in the student lounge. Karl and Lukas eagerly participate but Reinhold senses it's a ruse. After exposing an obvious ploy, Reinhold smugly celebrates by drinking a beer. The study group's true plan is revealed as they take photos of the Germans which are sent to Dean Pelton.
|The Dean tells the Germans that it's forbidden on campus for anyone to celebrate their ethnic heritage in order to prevent racism and nationalism. As punishment they will be banned from student amenities including use of the study room. Later, the study group triumphantly returns to the library only to be greeted by a student protest led by the Germans. The group is shocked to learn that they are perceived as villains who have been hogging the study room by the other students. Elsewhere, Chang turned himself into the police for his crimes last semester but ends up being bailed out by Dean Pelton. He now believes the amnesia is real since Chang has remorse for his past sins and is willing to help him. Back at school, the study group is in the cafeteria feeling down about their status on campus when their wallowing is interrupted by Professor Cornwallis.
|His sudden appearance causes Jeff to leap to the conclusion that Cornwallis set this all up to teach them a lesson but the Professor tells them he's there to inform them that they missed the first exam and have received a failing grade. Jeff is forced to admit that in this case he is the villain who manipulated this situation. He decides that reparations are in order and the group starts by renovating the dilapidated basement while at the same time repairing the group's reputation on campus. Sometime later, the group is in Study Room F having just finished their study session, happy to finally be back. Dean Pelton shows up and congratulates them for having made amends with everyone. He then asks that they keep the spirit of forgiveness in mind when Chang walks into the room causing the study group to start screaming.
