The Evenki abduct Neeko, Miljan, and Sabina. Meanwhile, Daniel, Sam, Joyce, and Johnny desperately try to contact the outside world from the research station, but make a startling discovery about their true role in what is going on.
While Johnny, Sam, Daniel, and Joyce settle in at the research station and learn more about the history of the area, Sabina and Neeko are forced to take defensive action when one of the missing contestants returns with shocking news.
As a fog envelops the settlement and the surrounding area, Johnny, Joyce, Sam, and Daniel try to get to the radio beacon. Meanwhile, the others stay at the settlement and find a startling discovery.
As winter arrives in the middle of summer, one group tries to make their way to the beacon while the remaining contestants search the abandoned producers' base camp for supplies.

As a mysterious phenomenon lights up the sky above the settlement, Sam and Daniel discuss relationships, Annie is surprised by Natalie's mixed emotions, and Carolina makes a big revelation. Meanwhile, Neeko tries to keep the other contestants under control but loses control himself.

After the death of one contestant, another one chooses to leave while he can. The remaining twelve contestants discover a food cache, but people become suspicious when another clue leads to a rifle... and the group discovers that someone has already taken it.
