The young salesman Eugene whiled away another dull day at work in a bookstore. That is why the proposal of the mysterious visitor to “get to know the human soul” seemed interesting to him, but he had no idea what he was agreeing to. The “teacher” quickly moves from theory to practice, marks out grades for uncompleted assignments in blood, and then refuses to provide any help at all, leaving the hero almost alone with some of the most cruel creatures of our world - the people around him. Will Zhenya be able to survive all this, having passed all the tests, or will she become another victim of an omnipotent being?
