The paths of science are inscrutable. Scientists' discoveries can be a breakthrough into the future, or they can turn into a disaster. Physicist Timofey Bodrov, working on the problem of unfolding the dimensions of the Universe, faces a difficult choice: continue the research of his entire life or recognize their disastrous danger for humanity and destroy what has been done. And a decision must be made immediately, before the results of the experiment fall into the wrong hands. The peaceful life of an armchair scientist suddenly turns into military action. Something happens that Bodrov could not even imagine, people come who under other circumstances he would never have met, questions that he never had to think about before demand answers.
