In a cozy country boarding house for the elderly, three inseparable friends - Sergei Petrovich, the father of the assistant to the Prime Minister himself, retired hypnotist Karen Zavenovich and the charming Margarita Nikolaevna are preparing to celebrate the New Year.
They are a little sad, joke with each other and write letters to Santa Claus (it is easier to find him sober than Father Frost). But something incredible happens: in a strange way, the gift of Cagliostro returns to Karen Zavenovich. This is where the most unexpected and incredible events begin to happen... On the eve of the holiday, when any miracles are possible and magic is in the air, three friends make their most secret wish - to become young for one night.
And when, with the last stroke of the clock, their wish unexpectedly comes true, the three friends get an incredible chance to do what they have dreamed of all their lives...
