|In Group Study Room F, the Save Greendale Committee throws a going away party for Troy before his trip. Britta reminds everyone it's okay to be sad Troy is leaving. The PA system interrupts with the Dean letting Abed announce his going-away present for Troy is a school wide game of "Hot Lava." Meanwhile, Abed incentivizes everyone to play by offering his comic book "Space Clone" valued at $50,000. Everyone scrambles to get ready for the competition as Abed starts a countdown. Hours later, Britta is searching for Abed while adhering to the games rules when she encounters Professor Duncan in the teachers' lounge. Duncan attacks but Jeff and Annie show up and save her.
|Britta joins them and they begin "centipeding" through the halls with chairs. Britta believes the lava game is Abed's way to put off saying goodbye to Troy. Jeff dismisses her theory as he spots loose chairs. When they approach, several students pop out of the nearby lockers. Ben Chang is the leader of these "Locker Boys" and demands their provisions. Troy and Abed make a heroic entrance and tell Chang to back off. The Locker Boys retreat although it's because of Buzz Hickey arrival riding an intimidating makeshift vehicle. Hickey drives through making quick work of the Locker Boys. The study group members escape with Abed telling the others he and Troy will meet up with them at "Shirley's Island."
|When Britta encourages Abed to say goodbye to his best friend, he orders Troy to strand Britta in the hallway. However, Hickey takes pity on Britta and invites her to join him. Elsewhere, Troy and Abed arrive at Shirley's Island, a peaceful demilitarized oasis inside the cafeteria. Shirley welcomes them all but turns less friendly when Abed asks her about something called "The Orb." Troy regrets how they treated Britta on his "last day", but Abed doesn't understand his meaning. They are interrupted by the arrival of Hickey and his army of "chair-walkers." Britta is with him and declares everyone should quit playing childish games and face their feelings. Hickey's army attacks and the ensuing battle claims not only Annie but also Jeff who is sent into the lava by Britta.
|Inside the Island, Shirley presents The Orb, a Zorbing sphere, to Troy and Abed who use it to burst free from the Island. They roll into the battle and dispatch the remaining enemies. They face off against Hickey and his Juggernaut in a game of chicken but lose when the sphere gets sliced. Troy and Abed retreat and are pursued by Hickey and Britta as the orb slowly deflates. They roll down a stairway to the basement and leave the crumpled orb. Abed suggests escaping but Troy favors making a final stand because the game has to end. Abed admits that it's not a game for him, he really sees lava instead of the floor. When Hickey and Britta show up, Troy explains the situation to get them to back off.
|Hickey doesn't care and knocks over the shelves which Troy and Abed are holding onto. Troy is still safe but Abed is forced to jump up into the rafters. When Britta eliminates Hickey from the game, Abed realizes that the floor is only lava because he refuses to let go of Troy. He decides to fall to the ground and pretends to be "dead." Troy prepares to forfeit the game but Britta comes up with a plan. They "clone" Abed, who is revived as a copy who can now let his friend go. Troy is "cloned" as well to remove his trepidation about leaving. Afterwards, the study group assembles outside the library to prepare to say farewell to Troy as his sailing vessel arrives.
|Britta tells Troy he's a better lover than Jeff and Annie is happy they've become close friends. Jeff confides that since he himself has never left the state of Colorado, Troy is now much cooler than he is. Shirley thanks him for putting up with her parental ways but Troy assures her she is the badass of the group. "Clone Abed" then informs "Clone Troy" that the cloning process included homing pigeon DNA which gives him a compulsion to return. Jeff worries that Troy will have trouble sailing alone. Troy responds that Pierce's will arranged for someone to join the trip to verify he doesn't cheat. His favorite celebrity LeVar Burton then appears from inside the ship and invites Troy on board. The rig pulls away as Troy and the study group wave goodbye to each other.
Troy asks LeVar Burton questions about Star Trek but, rather than criticisms of various episodes, he asks about the minutiae of on-set life.

During the Q&A session for the charity table read of "Cooperative Polygraphy " during the 2020 COVID-19 pandemic, Dan Harmon recalled the episode's tag originally showed LeVar Burton yelling at other drivers during a traffic jam (including using his Reading Rainbow clout over another driver). Harmon claims this version was shot and even edited, although none of the cast recalled ever seeing it.
