An epic journey up the Big Island's active volcano determines a million dollar winner!

Without a plane, the contestants find themselves in a manic road-trip race – all the way to the shores of Hawaii...

The Aftermath set - which has been moved to glorious Hawaii! Geoff and the Peanut Gallery are giddy – now this is an Aftermath. Added to the mix are returning losers and finally returning after six long weeks surrounded by Russians and meat is none other than Bridgette! Unfortunately for Geoff, Bruno the bear has come with her! But this Aftermath is all about taking sides, so the Peanut Gallery pledge allegiance to their favourite members of the Final Three. Little do they know that one member from each team will have to compete in a surfing challenge to win a prize that will aide their finalist in the finale. Of course, the surfing route goes directly over a lava spray into the awaiting jaws of a vicious animal!

The Final Four take a trip to the Badlands of Alberta, Canada - the world's richest hunting grounds for paleontologists. A creative dinosaur building competition pits the four of them against each other, and Sierra's broken heart actually helps her in building a very emotional dinosaur of betrayal. Alejandro faces his own challenge in the loser's spot. When Heather gets stuck in a big hole of her own making, he must chose whether to leave his biggest competition behind - or rescue the girl he cares most about. How inconvenient that they happen to be the same person!

With just four contestants left, the heat is really starting to ratchet up on the battle. Alejandro's choice to bring Cody to first class proves to be brilliant strategy as Cody is desperately grateful for a night away from Sierra's obsession with him and is now willing to do anything to help Alejandro. The plane lands on Easter Island where Chris announces an 'Easter Egg Hunt' through the gigantic stone Moai heads that line the island - with a difference, since each of the heads is made up in the shape of a former competitor. When each competitor has found their coloured eggs, they must race up a lava tube in the island's rock to deposit the eggs in the nest of a supremely angry Giant Condor.

The Serengeti, Tanzania. Cody is deliriously weak thanks to the love potion tea Sierra keeps pouring down his throat, so Sierra turns her knapsack into a baby carrier and lugs him around, playing both for herself and for her 'husband.' The challenge: secure gear for a Safari to hunt a ferocious and wild...Ezekiel! First, players must dodge soccer balls and hit plums with cricket bats to crack open gourds containing goggles, slingshots, and tranquilizer balls.

The next stop on the show's world-wide tour is exotic China, where Chris announces that each individual will be on their own for a race down the top of the Great Wall. Duncan and Alejandro work their strategic faux-friendship. Sierra, meanwhile, continues to tell Cody that they are married and he is forced to pursue desperate measures to lose her from the game. Blaineley cannily persuades Chef to help her cheat but he has a tougher time in the crazy and daring food-eating competition that follows, featuring all kinds of very authentic - and tough-to-swallow – local delicacies.

The contestants have a rather rude awakening on their return home to Canada - because they are dropped into the rushing waters of the Great Lakes, just meters from the destructive wonder of Niagara Falls! After a daring escape, they are startled to find that Chris is now dissolving the teams. He decides to take the opportunity to pair them up for what may be the most emotionally challenging competition yet, and teams of one boy and one girl must compete in races based on Niagara Falls' historical place as the 'Honeymoon Capital of the World'. After a blindfolded trust challenge leads each bride to a wedding gown, the couples must walk a tiny tightrope over the falls and get through 'U.S. Customs' (AKA Chef, in a little booth and a particularly foul mood.)

Geoff is thrilled to announce Blaineley is gone, doing a world tour of countries where Total Drama is a hit. But where's Bridgette? Blaineley appears and reveals that she tricked Bridgette into leaving the country instead! Bridgette calls in from Siberia, shivering, and begs Geoff to appease her host, a pissed off Blaineley 'SuperFan,' by singing a country song about Blaineley. Tonight's big announcement: someone from the Peanut Gallery is going to get sent back into the big game to compete for the million!

The frozen waters of Sweden. Owen tells Duncan Noah's theories (ie. that Alejandro is evil and majorly into Heather), and Duncan tries to make Owen see that Alejandro is the enemy while Alejandro works to regain Owen's blind trust. The challenge: first, each team must build a mystery object which turns out to be...a Viking ship! Teams must drag their 'ships' to water and sail to Chef to get their final task: pick a Captain then either race to the finish line, or try and sink their opponents by firing Swedish meatball cannonballs!

Australia. Gwen and Duncan can't believe they survived the last elimination round; both know they're still targets. Alejandro didn't eliminate Duncan because the punk may still be useful. So he leads Duncan into suggesting Alejandro seduce his ex, since it will throw both Courtney and Heather off their games. Courtney can't wait to lose and vote Gwen out - and if that means not doing her personal best, Courtney's willing to make that sacrifice. The challenge: an emu race up the Blue Mountains to Hanging Rock, followed by a bungie-jumping, sheep shearing competition.

Area 51. (Okay, technically, 52. But 51 is right next door!) The tension amongst the players is unbearable. Duncan's still enemy number one in Team CIRRRH, and Gwen's become the new 'Heather', despised by the rest of Team Amazon. The only one having a good time is Heather - finally, the target's off her back! The challenge: to sneak into Area 51's Black Box warehouse and steal a functioning alien artifact without getting caught by an elite Black Ops security detail.

Athens, Greece. Courtney is elated to have Duncan back – and Gwen is a bundle of conflicted nerves since she just kissed her kinda-friend Courtney's boyfriend in the confessional!

The refueld airplane finally makes it to London - and with DJ gone, only two teams remain! Amazons Gwen and Courtney are amazed to realize how much they have in common – and how pleased they are about it.

The Aftermath Set. Tonight Geoff and Bridgette (and their annoying co-host, Blaineley) have a huge task – they need to raise $500,000 so Chris can refuel the plane and get everyone out of Jamaica!

In the plane en route to Jamaica, DJ is sure his luck has changed. With lucky fish Irene at his side, nothing can go wrong.

It's an exciting homecoming for Chris, back to his birthplace on the East Coast of Canada and the storied Grand Banks of Newfoundland.

Paris – the city of love, and of the Louvre. Chris has hidden pieces of the world's most famous statues throughout the world's most famous museum, and the teams scramble to find and assemble the statues in the museum's renowned pyramid court.

The Peruvian jungle. Heather is miserable, still smarting from the Leshawna beat-down and missing a tooth to boot!

The German Alps. The teams are dumped into avalanche territory and have to sing softly or risk a ‘song-alanche.'

The Aftermath Studio. Geoff co-hosts with Blaineley because Bridgette's in the competition, unlike the Peanut Gallery of disgruntled almost-rans – Trent, Justin, Sadie, Katie, Beth and Eva.

New York City. Teams must get baby carriages from the Statue of Liberty's crown and race them through Central Park.

The frozen tundra of the northern Yukon. The challenge: jump ice floes across a frigid waterway, then pull a dogsled to collect your teammates and race to a finish line, all without freezing to death!

As the teams begin to gel – or not, in the case of the wildly different girls that make up Team Amazon – Chris announces that the competition's next stop will be Japan.

Now that the competitors have been separated into three teams (Team Victory, Team Amazon, and Team Chris Is Really Really Really Really Hot), Chris gives them their next challenge – a race to the Nile.

New season, new rules: Total Drama is back, and this time it's international! Chris and Chef are flying competitors all over the world (in a huge decrepit plane) to compete for a million big ones
