It seems like he didn’t drink, didn’t indulge in drugs, wasn’t diagnosed with schizophrenia either, but life turns into one continuous mess and you can’t remember what happened yesterday, or whether anything happened at all. Some things and people disappear, others appear or change beyond recognition. And all the attempts of the main character to prove something to someone run into a wall of misunderstanding and advice to quit drinking and heal his psyche. But the successful programmer Sergei Goshin knows perfectly well that he is of a sober mind and a strong memory. But why did the whole world around him suddenly go crazy? Trying to figure it all out, he meets a taxi driver on his way, who spends a long and difficult day driving his passenger to different places in the city in search of the disappeared past. Goshin tells him his whole story, and the driver, who at first chuckled ironically, soon gets involved in everything that is happening headlong, so much so that it doesn’t take long for him to go off the rails.
