Vitya and Raisa go to the Northern Economic Forum in search of investments and decide to hold the Russian Biathlon Cup in Polyarny. Lomaev's companions put the latter in front of the fact that no Cup should take place in the Polar. And Nemolyaev is taking Antonina on an exotic date.

Polina suggests Bolt and Angela to start training on a dog instead of the children. At the same time, Tolya and Kolya are implementing an audacious plan to sell a very special dog of Kolya's father. Of course, these two stories cannot but intersect. And Vitya comes into conflict with his mother-in-law on the basis of his son's alleged preferences - ballet or boxing? That's the question.
