The episode begins with
Cobra forces led by
Destro (
Isaac Singleton Jr.) attacking the
Taj Mahal. They are intercepted by
G.I. Joe troops led by
Flint (
Bill Ratner). Among the force is the (rather dysfunctional) study group; Annie (
Alison Brie), codenamed "Tight Ship", who questions their orders; Britta (
Gillian Jacobs), codenamed "Buzzkill", who comments on her suggestive outfit with inappropriate language; Shirley (
Yvette Nicole Brown), codenamed "Three Kids", who is too busy talking to her kids on the phone to focus on the battle; and Jeff (
Joel McHale), codenamed “Wingman”. Jeff shoots down Destro's plane, but takes things too far when he shoots out Destro's parachute. A surprised Destro falls to his death, causing Flint and the rest of the Joes to stare in horror. The quartet are charged with violence, suggestive language, and mature situations unbecoming of G.I. Joe at a
court-martial presided over by
Duke (
Michael Bell), Flint, and
Scarlett (Mary McDonald-Lewis). Wingman defends the first killing in G.I. Joe history by countering it should be their duty to eliminate Cobra because it is a ruthless terrorist organization, but the four are sent to jail. In the jail, the Group meets "Fourth Wall", played by Abed (
Danny Pudi), in the adjacent cell. Fourth Wall explains that they are in a cartoon and that he has infiltrated a Cobra dig site called "Greendale". Wingman briefly loses consciousness, sending him to a live-action, mock G.I. Joe commercial featuring three young boys playing with G.I. Joes and their accessories. Meanwhile, at Cobra Headquarters,
Cobra Commander (
Rob Schrab) delivers a eulogy at Destro's funeral. He is interrupted by "Vice Cobra Assistant Commander", played by Dean Pelton (
Jim Rash), who delivers news of an energy surge at the Greendale site. Cobra then initiates an attack of the G.I. Joe base to avenge Destro's death. Cobra bombs a hole in Wingman's jail cell, allowing the Group to escape. Wingman tries to help out in the battle but just ends up killing more Cobra soldiers and accidentally setting
Lifeline on fire, causing him to burn to death. The Squad leaves in a “Submachopter”
tiltrotor, and Fourth Wall suggests going to the site at Greendale. The mention of the word causes Wingman to lose consciousness again, sending him into another live-action G.I. Joe action figure commercial. He regains consciousness, and the Mutineers arrive at the Greendale site. The Mutineers easily defeat the opposition and enter Study Room F, where Wingman realizes that he works at Greendale as a teacher named Jeff Winger, this cartoon reality is in his imagination, and he is unconscious because he drank a bottle of
Scotch whiskey and took anti-aging pills from Koreatown. He returns to the group and explains that he took them because he has been lying about his age. Fourth Wall informs him of the different layers of existence, where he is currently in the 1980s cartoon layer. He explains that Jeff sees visions of the next layer, the toy commercial plane, which separates him from the real world where he must go to confront the reason for the hallucination. Jeff says he doesn't want to go back because he wants to be in G.I. Joe, as he is immortal in this cartoon world. Just then, Cobra and G.I. Joe forces intervene to reveal they have joined forces to become "Jo-Bra" and capture Wingman, as his ability to kill means that he is the biggest threat to both of them. Cobra Commander and Duke ask Jeff questions about real life that make Jeff realize he cannot live in this cartoon universe forever. Jeff tricks them using his jet pack to escape the cartoon and enter reality where he is on a hospital bed, surrounded by the members of the Save Greendale committee. Jeff reveals that he's 40 years old, to no surprise of the group; as they were aware that he wasn't around his early 30s. They nevertheless support him and say he should not have been embarrassed to reveal his age. He tells them to bring it in for a hug, and they all laugh while the camera fades to black. The animated end scene shows Buzzkill catching two kids spray-painting their names onto a park structure. She botches a
Public Service Announcement and gives a cynically complex message before Fourth Wall intervenes to give a short message: "Graffiti is bad. Go play sports." ==Cultural references==
