Jan Ťapal is a talented and brilliant creator of computer programs. Like most of his colleagues, "jokes" live in our point of view outside reality, in the world of incomprehensible features, a combination of numbers and symbols. There, his interest, his real life, takes place, beyond the usual worries of everyday life. The reader begins to uncover the dramatic events when his world is disturbed by the wife's request for divorce. The reason is his infidelity - in the parallel world! Tapal managed to create an artificially different, parallel world in which there are no figures and imitations of our world, but by real persons, atlas similar to ours! It looks as if we were watching an authentic film in which we play. The form of people is indistinguishable from the original! Gradually, it is successful that the "original" from our world can affect emotionally and in some thoughts and lead its "copy". It is not possible to break away from the screen where we see ourselves in a real parallel world! It is a bit different and seems better, repaired to our liking, a little different from our one we live in. Who would not want to pass for a moment to live there and live a different life, play a different role than before? Fix your life!
