<P> Like Total Drama Island, this season is a fictional reality show that follows the competition of thirteen new 16 - year - old contestants at Camp Wawanakwa, a summer camp on a fictional island located in an unspecified area in Muskoka, Ontario . However, since the island has been forgotten and left alone for the past two seasons, the island has been used as a toxic nuclear waste dump, transforming it into the perfect location for the most dramatic and brutal challenges yet . The new cast of campers must then participate in competitions to avoid being voted off the island as they all try to get ready to compete with some of the most popular original contestants in the fifth season . They spend almost 2 weeks (13 days) in this camp competing in challenges for immunity and at the end of the season, one winning contestant will have the chance to win one million Canadian dollars . The competition is hosted by Chris McLean (Christian Potenza), who is assisted by the camp's chef, Chef Hatchet (Clé Bennett). </P> <P> At the beginning of the season, the thirteen campers are placed onto two teams, the Mutant Maggots and the Toxic Rats . In each episode, the teams participate in a challenge, in which one or more campers can win invincibility for their team . The losing team is called to the elimination ceremony at night, where they vote one of their own members off the island . At the ceremony, Chris declares which contestants are safe by calling their name and giving them a marshmallow, while the one whose name is not called is eliminated from the game and given a radioactive marshmallow . The eliminated camper is then taken to the Hurl of Shame and catapulted to the Playa de Losers . However, an eliminated camper can still come back to the game if they find a wooden Chris head . </P> <P> About halfway through the season, the Toxic Rats and the Mutant Maggots are disbanded, after which the challenges continue; the winner of each challenge then only receives invincibility for him or herself, whereupon a camper without invincibility is voted off the island . This process of elimination is continued on until two players (Cameron and Lightning) remain on the island, where then they are subject to a final contest . At the end of the season, Cameron is crowned winner of the season and is given the million dollars by Chris . Lightning however, wins in the alternate ending, which airs only in the United States . </P> <P> Total Drama: Revenge of the Island premiered on both Teletoon and Cartoon Network 2012 . Teletoon has aired Total Drama: Revenge of the Island on Canada on Thursday nights at 7: 00 p.m. EST from January 5, 2012, to April 12, 2012, while on June 5, 2012, the U.S. started airing it on Tuesday nights at 7: 30 p.m. EST on Cartoon Network .
