Artem and Gan find themselves on the other side of the gap - in a world completely different from ours. At this time, Kaya barely gets out of the Red City, panic-stricken and almost buried under the snow. The balance between the worlds is broken, and no one knows how much time is left to find the key to the solution. While Kaya and a group of daredevils go to an abandoned station, Artyom and Gan embark on a dangerous journey through other lands, where every wrong step can lead to a trap. Will they have time to close the gaps before something irreparable happens? And most importantly: will they be able to return home?
