Lightning and Cameron, the final two, are told to vent all of their feelings in the confessional at the beginning of the episode. They then both watch video messages on a television from their relatives at home: Cameron's mother and Lightning's father. Lightning's father bets his championship rings that Lightning can win. They then arrive at a massive arena where Chris, Chef, two interns, and the eleven previously-eliminated contestants are watching them from the stands. A pile of junk is then dropped into the middle of the arena, and the two finalists must find a way to use some of the junk as either armor or weapons for the duel that will follow between them. Lightning creates a rather crude set of armor with ankle plates, a chest plate, a pan as his helmet, and a plastic mannequin's leg with nails sticking out of the top. Cameron at first appears to have nothing, but then reveals a mechanical suitcase that he created that turns him into Iron Man. The battle then begins, and over time, the two battle for so long with no clear winner that Chris later decides to make it interesting and drops every mutated creature from the island into the arena, only for the creatures (including Ezekiel) to start attacking everyone. During the attack, Cameron tries to save the other contestants from the monsters, while Lightning keeps attacking Cameron only. Eventually, one of Cameron's iron suit's abilities causes many of the barrels of toxic waste to magnetize to Lightning's body armor, giving Lightning white hair and causing him to get tired and black out. Cameron then gets tired too and falls down on top of Lightning, making Cameron win the final challenge. Chris then comes and crowns Cameron as the winner of Total Drama: Revenge of the Island and the new recipient of the million dollars. As Chef and the thirteen contestants sail away on a boat, Chris attempts to detonate a bomb placed on the underside of the boat, only for the bomb to go off on the dock directly beneath Chris, as Chef switched the bomb. The RCMP then descends on the island saying the island is under government protection. Chris is ordered to be quarantined, while Chef and the rest of the cast flee away and cheer.
