In December 2017 it will be hot! The friendship between Zhenya and Boris will almost burn in the fire of a family scandal; deeply pregnant Snegurochka will go to Odyssey by families of Nizhny Novgorod; desperated Galya from Novosibirsk will do anything to spend the night with her beloved doctor; an extreme campaign in the woods beyond the tree will be a test of strength for a young hipster from Tyumen and his potential stepfather. New and familiar heroes of "Yolki" fall in love, quarrel and make peace, commit heroic deeds and fall into a mess, just to find a real soul mate on New Year's Day, like one brave boy from Khabarovsk who escaped in search of a new mother to Moscow. And only a miracle can help them... or the whole country!
