The people that kidnapped Neeko, Miljan, and Sabina turn out to be the Evenki, the dangerous local tribe mentioned in Miljan's journal. They drag their hostages out to a tent where they're reunited with Annie and Esther. And Annie's in the next tent over. Everything's very ominous, although Sabina gets to meet the mysterious little girl she saw in the forest. Her name is Sasha, and she's the daughter of an American scientist. Eventually, a shaman comes in and takes some psychoactive mushrooms. His spiritual visions tell him to just send the outsiders to some white people they know about. So really everything's going to be fine.
At the Science Institute, Daniel has to break the news to everybody that just because he made a computer work doesn't mean he has an Internet connection. But Sam gets him to work on making the radio work without the collapsed radio tower, which involves taking forty feet of wire and laying it along the edge of the roof. This takes a while, so there's plenty of time for Johnny to find two spare Revealers in the laboratory, and for Joyce and Johnny to get into a fight, then make up. By kissing. Daniel falls off his ladder, but he gets the antenna all set up, so the radio's working again. And with the help of a cameraman, they actually make contact with someone who might come rescue them! They make no perceptible effort to establish a connection between the Revealers in the lab and the Revealer that was part of the reality show.
Before the Evenki take their hostages away, they undergo an attack by the mysterious Mangini, or "Valley Men." So there are still some monsters around here after all! The expedition takes a brief detour past the old camp, where Miljan takes Esther's bag of whatever she stole from the Revealer. Then they pass what appears to be a cursed igloo before their Evenki guide tells them they're on their own. All they have to do is go through Mangini territory to the tune of one forest and one mountain peak, and they'll be home free!
Neeko, Miljan, and Sabina are being walked through the snow. Neeko won't shut up about "Where are they taking us?" and "How many of them are there?" They're moving in single file, presumably to hide their numbers. That's a Star Wars reference.
At the Science Institute, Johnny wants to go online with Daniel's computer. He tries to explain that there's no Internet, and Joyce demands that he hack in to something. Sam helps Daniel talk Johnny out of the idea that all computers have the Internet in them. Then Johnny tells Daniel that Irene is probably dead, since she's had three days without a rescue team. So Daniel stomps out of the room, because that's Johnny's fault or something. Then Daniel mopes on a bed while sad music plays.
Eventually Joyce comes in to talk to him, and he mopes out loud about how he failed. She gives him some boots without mentioning that she pulled them off one of the dead guys. He thinks coming to the Science Institute was a stupid plan, because they're not any closer to being rescued. Well, they have warm clothes and food and better shelter, so that's a lot like being rescued. Joyce tells him he's strong, which isn't really true. She would like him to fix the radio, which sounds like a worthwhile project. He pulls himself together and heads out to look at the beacon. It's all smashed up and laying on the ground, so I'm not sure how much success he's going to have.
Neeko, Miljan, and Sabina have been led to some teepees in the snow. They're shoved into one of them, where someone says, "You're alive!" It's not clear who says it or to whom, but it leads into the credits, so I assume we'll get a better look at the situation in a minute.
After the credits, we learn that the teepee contains Esther and Annie. Esther warns the rest of the cast that "they" (the people outside with the guns) don't like it when you talk. Irene's apparently in another tent. Miljan peeps under the side of the teepee, and I guess a cameraman does too, because we see some footage of people standing around.
Daniel and Sam look at the beacon and it's kind of a wreck. Daniel is not optimistic, but he looks at a torn cable. He has a plan involving something called a "loop antenna," which basically involves putting some wire around the roof of one of the buildings. Sam is prepared to provide muscle for this operation, so they're onto Phase I: Find Some Wire.
Meanwhile, Joyce is rummaging through the lockers, looking for cell phones. Johnny calls it "looting," which is a little unkind. He's creeped out by this place, because it's full of charts and graphs. And dead bodies, which I think are much creepier than charts and graphs. Anyone can chart and graph something. Johnny thinks the dead people found out something they weren't supposed to know. I think they really ought to go look at the security footage to find who shot the place up. But that's just me.
