A young engineer, an employee of one of Moscow’s defense research institutes, goes on vacation with a group. A thunderstorm will catch them in the forest. Thunder, heavy rain—lightning strikes Dmitry. It would have killed someone else, but he was lucky: they managed to get him to the hospital, even though he had burns. After the incident, he gained incredible abilities, including the ability to hear other people’s thoughts. Quite quickly, he entered the ranks of the initiated and began fighting the non-humans—the dark dwellers of underground depths.
