Total Drama: Revenge of the Island

The fourth season finally begins, introducing a whole new cast, set at Camp Wawanakwa, which has turned into a bio-hazardous waste dump. The thirteen contestants are divided into two teams, the Toxic Rats and the Mutant Maggots. Two contestants build a close bond, and one contestant manages to annoy her entire team into eliminating her that night.

As the competition narrows down to twelve, the campers must compete in the first part of their challenge; a tell-all trivia game which ends up embarrassing several contestants. Due to the problems in round one, the host makes the second round miserable for both teams. Ironically, a nonathletic camper ends up winning the physical-oriented challenge for his team, sending the other team to the elimination ceremony. In the end, someone becomes too focused on her image and is quickly voted off.

The remaining contestants take part in a frigid challenge including climbing a mountain and a snowy capture the flag game. One of the Maggots asserts themselves further as team leader as a Rat continues to ruin their team's chances regardless of other's abilities. Someone gets fearful of their secret being discovered, but it comes through with another victory for their team. Ultimately, through a cruel trick, a camper is thrown off the island while someone else returns in a fame-desperate move.

The two teams are sent into the the woods on a scavenger hunt, where one camper's alternate personality hooks up with someone else, despite their true self being in love with a different camper. Meanwhile, someone continues to sabotage their team's chances, but fails in the end due to someone else persisting towards a victory. The losing team attends their first elimination ceremony, where someone volunteers for elimination, but ends up on the winner team, while an intern is eliminated again.

As one team deals with their newest member, the other is severely divided by one contestant, who shares feelings for two girls at once. When the contestants' most prized possessions start vanishing, one player initially accuses their teammate, but then places the blame on someone else. Although they figure out the true scheme, it is not enough to prevent elimination.

As one team suffers dysfunction after a particular gamer feels as if they are lacking in the macho department, the other team shows problems with the over-macho nature of another and a persistent conflict of two others. In the end, a contestant suffering from withdrawal loses the game, but wins the heart of the girl of his dreams. Later, in a shocking surprise twist, the host forces two contestants to switch teams.
