Ilya Mironov teaches at the Polytechnic Institute and doesn’t seek a relationship—something he’s perfectly content with. But his grandmother, Aglaya Rudolfovna, doesn’t agree with that. She dreams of great-grandchildren and constantly reminds him of her advanced age. She convinces her grandson to fulfill her request and go with her to a foreteller to find out what the future holds for him. Yana Reshetnikova, an energetic student of the same institute, has a complicated relationship with associate professor Mironov. But one day she learns something interesting about him—and decides to use it to her advantage.
