A story about love that never happened. 1975, 23-year-old Volodya met young Katya at a dance and, as they say, fell in love at first sight. But, alas, the relationship between them never began. The reason for this was the age difference, which seemed too big to 17-year-old Katya, and the fact that the girl set herself a goal in advance: to learn first, and everything else later. Life brings them together twice more, in 1981 and 1997. It no longer seems to Katya that there is such a big age difference between them, but, as they say, the train has left.
