The ways of science are not for us to know. Discoveries by scientists can become a breakthrough for the future—or lead to catastrophe. For physicist Timofey Bodrov, who is working on the problem of the Universe’s dimensional unfolding, a difficult choice arises: to continue research for the rest of his life, or to acknowledge its deadly danger for humanity and destroy what has been done. And a decision must be made immediately, before the experiment’s results fall into someone else’s hands. A peaceful life of a laboratory scholar turns into combat action overnight. What Bodrov could never have imagined happens: people arrive with whom, under other circumstances, he would never have met; they demand answers to questions he never had to consider before.
