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".

In a small northern coastal town, a woman's teenage son disappears. There is a celebration in the city. The heroine, seeing no other way out, goes to the family of her ex-husband, the father of the child, in the hope of finding her son there.

Escaping from her husband's abuse, Sasha goes to the very edge of the country - to Teriberka. The long road teaches her absurd but necessary lessons: how to persuade stubborn cars, run away from "antelope hunters", and most importantly - find and accept help in the most unexpected places. But the cherished sea will remind: to build a new life, you need to return the most important thing.
