Sonia falls down the stairs and gains the ability to see what other people can’t. The Spirit of a Shaman comes to her. Sonia can’t believe what’s happening—her thoughts are focused on passing her exam. The Spirit helps her pass by telepathically sending her the answer to her ticket. Then he asks her to call him the Invisible Man, tells her she needs to find a map, but doesn’t say which one—he simply sends her soul into a parallel world, where she also ends up in the body of Taisiya. At first, Sonia doesn’t believe she can complete the Spirit’s task, but events unfold in such a way that success depends only on her—because her soul has the extrasensory abilities of a searcher.
