On the way to the White Sea in the city of Kantalahti, members of the Stalker group are forced to make a stop, which radically changes their plans. They are convinced that the Turmoil has affected not only Monchetundra and its surroundings: here, in the wild polar forests, there are also its creations - both in the form of evil, disgusting creatures, and in the form of previously unknown anomalies. It seems that one of them became the cause of the disaster of the Kantalahta airship, which the stalkers now have to find. And there, on an abandoned highway, the group suddenly has one more stalker. More precisely, at the stalker, although she herself had never even heard such words. And this is not the last change in the composition during the events that happened next. At the head of the group are now two people at once - Lom and Kapon, by the will of fate, or rather, the same Cloudiness, who became the dual Lomon. And he, the dual one, will have to solve problems that his two hypostases could not even dream of in the most fantastic dreams.
