Three friends, who were fans of Ivanushki International in their youth, meet and decide that they have never done a single crazy thing in their entire lives. They decide to fulfill their old dream and go on a fan tour for "Ivanushki" in the south of Russia, hoping to escape from their problems for a while. But the 15-year-old daughter of one of them ends up traveling with them.
Arriving on an excursion to St. Petersburg, classmates Dana and Lyova witness the theft of the famous "Chizhik-Pyzhik". According to legend, if you make a wish and get a coin on the pedestal of the monument without dropping it into the water, it will surely come true. But "Chizhik" is gone. Does this mean that the guys will never be able to realize their dreams and Lyova's parents will still get divorced, and Dana will not become a famous blogger? Courageous schoolchildren rush in search of kidnappers, hiding from teachers, parents urgently summoned from Yekaterinburg, policemen and even from themselves.... "Peter the Great".
