"Welcome to the Total Drama Aftermath! We are here in Hawai'i getting ready to see who takes the million home: Sierra, the Uber-Fan, or Katie, the Sweet Girl." Geoff introduces.
The scene changes to Chris, also giving a recap. "Last time, the final three raced to Hawai'i. Annoying Blaineley tried to host the show and then helped Sierra make it to Hawai'i first followed by hitchhiker Katie which caused Alejandro's reign of terror to end. Who will win the million? Find out now in the epic finale of Total Drama World Tour!"
Chris then addresses the two girls, standing on the beach. "Your challenge is to build pineapple statues of each other and then race up this volcano and toss the statue in. The first girl to toss her statue in wins the third season!" Chris explains.
Sierra and Katie look at each other, happily before frowning.
Sierra: (Confessional) Katie may be my friend, but it's time to put my game face on!
Katie: (Confessional) Sierra is a friend, but she is going down!
"You will pick two members from the peanut gallery to bring you pieces of driftwood and pineapple from that stash over there! The first person to finish gets a wheelbarrow to help them when they go up the volcano." Chris gestures to the pile. "Sierra gets first pick!"
Sierra scans the audience and smiles. "I pick Cody and Heather!"
"What?" everyone but Heather and Sierra ask.
Sierra: (Confessional) Heather is good in the game, no doubt, so I could use her to help me.
"Now…Katie." Chris continues.
"I pick Sadie and Leshawna!" she answers.
"Now go!" Chris says.
What follows is a flurry of activity. Sierra and Katie try to tell their respective helpers to gather what they need and build their statues at the same time.
Finally, Sierra finishes first and gets her wheelbarrow. "Bye Katie!" she says, half-earnest and half-bragging.
"I need that pineapple!" she cried and Sadie runs and gives it to her.
Katie inserts the head onto the body and twists it before smiling. "I got it!" she squeals.
"Go!" Sadie and Leshawna urge and Katie runs as fast as she can, but realizes the statue's too heavy.
Soon enough, Sierra arrives to an obstacle, which takes the form of a pit of lava with heavy objects held up by string over it.
"What do I do?" Sierra asks and Chris arrives, with Cody, Sadie, Leshawna and Heather.
"You have to take your statue and carry it over the lava pit by jumping on the stones, but be careful! The objects could be let loose by your opponents' helpers. You can also cause your opponent to have to dodge obstacles by making your helpers cut the strings attached to this log!" Chris instructs as Katie arrives.
Sierra jumps with her statue as Katie tries to catch her breath.
"Sorry Sierra!" Katie says as she begins to jump. "Cut a rope!" she cries.
Leshawna cuts one and a log nearly hits Katie. "C'mon!" she yells.
"Sorry!" Leshawna says.
Sierra smiles a bit and says "Cut a rope!" as she advances closer to the other side.
Cody cuts a rope and a cage drops down on Sierra.
"Codykins!" Sierra objects.
"Sorry!" he apologizes as Katie runs past her and gets to the other side.
"May the best girl win!" Katie smiles.
Sierra growls and pushes herself against the cage. The cage door opens and Sierra runs out.
At the top of the volcano, 22 anxious competitors await one of the final two.
Katie arrives and some people cheer. Suddenly, Sierra arrives.
A race ensures. Sierra pushes Katie behind, but Katie soon runs ahead, before getting knocked away by Sierra who suddenly stops in front of the volcano.
She is about to throw her statue in when Leshawna, who standing with the group, cries out "Oh look! Cody's hurt!"
Sierra looks behind her, unaware of the trick Leshawna is playing, for Cody as Katie picks herself up and runs to the volcano where she throws her statue in.
"Katie has won Total Drama World Tour!" Chris yells happily.
"Sierra!" Cody arrives, looking unhappy at her loss.
Sierra realizes what happened and frowns at Leshawna and then hugs Katie happily. "You deserved it! Good job!" Sierra smiles.
Katie squeals happily and runs to Sadie and Leshawna. "I won!"
Suddenly, Tyler sees a sign that says "No pineapples." "Uh, Chirs?" he begins.
"Not now!" Chris says and gives the suitcase with the million to Katie.
The volcano shakes.
"Chris?" Tyler asks.
"I'll give half of my money to you, Sierra, because you were a good friend." Katie promises.
Sierra squeals.
"Chris!" Tyler yells.
"What?" he cries.
Tyler points to the sign and Chris reads it before whispering "Uh-oh!"
The volcano shakes and everyone runs, screaming.
Alejandro is the first to leave, but stops for a second causing him to be trampled by everybody.
Soon enough, the volcano erupts, but by then, everyone…except Alejandro…is safely in the water.
"See you next season with an all new-cast!" Chris says as everyone swims away.
