Colonel Vetrov's group found itself on the threshold of a strange, incomprehensible and unknown world. There are different heavens and earth, different laws of the universe, different life. No human has ever crossed its boundaries. But there is a first time for everything. It just so happened that Vetrov has no other way. It is in this world that the true enemies of humanity hide. Who are they? How were they able to escape the all-seeing eye of the almighty Creators and deal them a fatal blow in the back? Does the coveted alien module really exist or is it a ruse by which the Master forces a select group to follow his unknown plan? The answers to these questions can be both salvation for human civilization and its death sentence.
