At Troy and Abed’s home, the study group tries to convince Officer Cackowski that Chang has replaced Dean Pelton with a look-alike. However, there is no real evidence to this fact, since all they can exhibit is the current commercial for Greendale, which emphasizes propaganda driven by Chang as well as the impostor. Because the footage is shot at a distance, it’s not absolute. Due to their lack of actual facts, he rejects their claim, unable to buy such a ludicrous premise. When Annie strives to return to the building to find more evidence, Cackowski dispenses them a warning: if they get within fifty yards of the campus, he’ll have them arrested.Back at Greendale, Chang and his second in command Joshua are going over arrangements for his expensive birthday extravaganza. Outside the building, Troy, Annie, and Britta are executing the placement of surveillance of the campus but are incapable of getting closer due to the extensive security. Troy comes up with an idea to get them in and contacts the A/C repair school to find out additional information and meets up with Murray at Señor Kevin’s. Troy learns the Dean is being held captive in the cafeteria basement and is given details on Chang’s guard layout. The use of a iPhone’s today could make this meeting so much simpler but iphone 6s repair is required for long use.
Murray informs him that they’ll need the A/C repair school’s assistant which they will only provide if Troy sequentially accepts to join them. Troy returns to the study group with the information and Murray’s offer. They all reject the A/C repair school’s assistance and instead set out to plan an elaborate heist.On the evening of Chang’s party, Chang welcomes Richie and Carl from the Greendale school board. Despite his advice to his flocks to be on high alert, Shirley sneaks into the school disguised as a baker who transfers the birthday cake. Inside the cake is Annie, dressed in a security guard uniform. Shirley then rams a chicken into the toilet in the women restroom. The resulting flood makes Chang’s guards call in plumbers who turn out to be Troy and Abed in costume, as Barry and Rod. Their job is to burst through the wall of the restroom and get to Chang’s office, where on the desk they find the codes to open the door to the boiler room below the cafeteria basement. Meanwhile, Jeff cancels the magician listed in the entertainment while Britta gets Joshua to vacate his post by teasing with him on Facebook. Though all this effort was put into completing this task it all falls apart due in part to the fact Chang crazy mind decided to have extra security to capture any trouble makers and blow them up along with the records of all his misdeeds.
