Merry Christmas!

Plot
The episode opens up with a Christmas party in first class, and the contestants are singing Do They Know Its Christmas? . Then, the Christmas party continues, and everyone is in the Christmas spirit. There are interns milling about everywhere, each dressed like an elf or in Christmas attire, performing different tasks like pouring hot chocolate or bringing cookies. Everyone is exchanging gifts, and Chris is watching from a room full of monitors. He says this Christmas is about to get a lot more interesting. The plane lands in a small village at an unknown destination. Chris tells the contestants to meet in the village inn and they do. They see the entire village there, about one hundred people and are curious why. It turns out everyone here hates Christmas, because every Christmas an unknown monster goes and wrecks people's houses, forcing them to stay at the inn every Christmas. Chris says today's challenge is to get the Christmas spirit into these people.

The contestants decide to split into groups and the groups all take different approaches. Nupur, Joseph, Katie and Colin decide they're going to put a giant Christmas tree in the town's plaza and make it look beautiful. Colin goes out to find a tree, while the other four go get decorations.

Kacvinsky's approach is to catch this "unknown monster" to keep it from terrorizing the town. He takes Caroline, Lizzie, Nathan, Ian and Emily to go try and solve the mystery. They start by beginning to interview the townspeople, but they aren't exactly thrilled about being interviewed.

Caelan, Sam, Andy, Jen, Clayton, Nathanael and JP decide that the best plan is to rebuild the houses and decorate them for Christmas. They go to the village's market and being buying some toys and decorations. They see Nupur, Joseph, and Katie there, and the two groups begin racing to get as many decorations as they can, both eventually wiping out the store's decoration supply.

In the meantime, Kacvinsky has a pad full of notes, and his group goes to investigate the most recent destroyed house. They come to see just half of the house destroyed, and not the full house. Emily points out that it's the side with the chimney, and Kacvinsky makes note of that. They then head to the next house to see exactly half of the house wiped out, also the side with the chimney. Ian points out though, if it was involved the chimney only the chimney would be destroyed, not the whole half of the house. Kacvinsky agrees, but says they should look around the chimney anyways. Lizzie and Caroline go and pick up the bricks and try to figure out if there's something special about them, while Nathan stands guard in case the monster returns.

Sydney, Serena, Channing, Myra, and Ruchi decide that gift giving will give them the holiday spirit. They head down to the market, but all the Christmas supplies have been wiped out by the other two groups, including the wrapping paper. They realize they are going to have to improvise and go out to look for presents.

Ashton, Cooper and Liz are standing in the Inn, with not a clue what to do. The other four groups have already made great plans and are out doing stuff, and the three are at risk of losing the challenge.

Back at the house re-building, JP is annoying Caelan a lot. He keeps apologizing for asking to vote off an alliance member, and Caelan keeps reassuring him it's ok because he also voted for Catherine, but JP doesn't believe he is being serious. This annoys the other house builders too. They finish up the first house, but have many more to do.

In the meantime, Lizzie points out that not all the houses have been destroyed, and that means the monster will make more appearances. There are six houses that haven't been destroyed, so the six of them split up and each take a house. The six hug, wishing each other luck and telling each other to stay safe.

Back at the team putting together the Christmas tree, Colin managed to find a gigantic tree that will work perfectly as their Christmas tree, and Nupur snagged a ton of Christmas lights back when they were shopping. She climbs on the roof of one of the buildings in the plaza, and lassos the top of the tree and swings around the tree. Katie is lobbing ornaments strategically on the tree, and Joseph tries to copy Nupur with the garland around the tree, but is unsuccessful, causing Colin and Katie to laugh.

While the six are standing guard at the houses with the families, the lights at Lizzie's family's house goes out. Her family is a single mother with a little boy. Lizzie reassures them that nothing is going to happen, but then an evil Santa bursts through the chimney, and begins wrecking the house. Lizzie jumps at him, and tries to tackle him to the ground. She is about to unmask him when he rolls over on top of her. She screams as the screen cuts to black.

The other five at the nearby houses rush to Lizzie's house to see Lizzie lying there, frozen. Nathan says there has to be a pattern, and Emily realizes it is, they get farther and farther from a certain point...the Inn. They go to the next closest house to the Inn, and this time they are ready for the evil Santa.

Caelan's group has finished re-building the houses, but they are all exhausted. Despite this they push and begin decorating, each choosing a house to focus on. There are seven of them, and many houses, so they go to find help, and finally Ashton, Cooper, and Liz have something to do and help decorate the houses. Nathanael and JP talk about how excited they are to let the families know that their house is rebuilt for free.

Sydney's group has bought all the presents and found a bunch of wrapping paper in the dumpster that was thrown out because the citizens of the town hate Christmas. Channing accidentally wraps her hair in, causing Myra to laugh, and Serena carefully ties a ribbon, paying close attention to detail. Once they wrap all the presents, they decide to put them under Nupur's group's big Christmas tree, that was finally decorated. Ruchi and Colin begin sprinting to the Inn to get the townspeople.

Evil Santa finally attacks the house Kacvinsky, Ian, Nathan, Caroline, Emily, and a now defrosted Lizzie by the fireplace are waiting in. Caroline throws a sack over his head, Nathan hits him over the head with a fireplace tool, Kacvinsky kicks low and trips him, Lizzie and Emily tie him up, and Ian grabs him. They decide to bring their prize to the plaza for the unveiling. By this time Caelan's group plus Ashton, Liz, and Cooper finish decorating all the houses and also head to the plaza.

Ruchi and Colin come back with everyone from the town, about twenty more people from the un-destroyed houses. When they get there, all the lights from the tree and all over the town from the newly decorated houses light up, and the kids of the town rush to open their presents. Jen is running around handing out pictures of the newly re-built houses with all the decorations, and Kacvinsky unmasks the evil Santa to be none other than the Inn keeper, who wants to make money every Christmas. He would destroy the half of the house with the chimney so the families would be too cold to stay in their houses.

A star mysteriously appears on the top of the tree, and a ho-ho-ho is heard while something flies off into the distance. The contestants sing Merry Christmas Day. Chris tells them that they all completed their challenge, and is super impressed, but since they all did so well, that means no one wins immunity and anyone can be voted off. The contestants board the plane, which is all decorated for Christmas. Chris tells them unlike usual, no one is allowed to talk about elimination.

At Christmas dinner, no one talks.

At the elimination ceremony, Chris reveals the item of safety is a Christmas present. The first name on it is the first person safe, and they open it to reveal another box with a second name. This repeats twenty four times, until there is one contestant who didn't open the present.

After everyone votes, Chris brings out a giant present. He reads the gift tag, and the first person safe is Andy. Andy, ecstatic, unwraps the present to reveal Kacvinsky's name. He unwraps it to reveal Caroline, who in turn unwraps it to reveal Ruchi. She unwraps it to reveal Myra, who unwraps it to reveal Sydney. The next names on the presents are Nathan, Ian, Colin, Cooper, Nathanael, Nupur, Liz, Ashton, Katie, Clayton, Channing, Sam, Emily, Joseph, and Lizzie.

This leaves four contestants not safe, JP, Jen, Caelan, and Serena. Lizzie unwraps the now significantly smaller present to reveal it's for Jen. She unwraps it and Serena's name is there. JP and Caelan both look really nervous. Serena is about to unwrap the present, and the name on the present is...

..........Caelan.

He unwraps the final present to reveal a little barfbag full of airline-issued peanuts, causing him to roll his eyes. The contestants look bummed, given spirits had been so high after the Christmas village, and everyone goes up to hug JP. He doesn’t understand why, but is happy he made it this far and takes the Drop of Shame.
