Sasha, Daughter of CPSU dignitary, after a successful high school graduation passes her exams at a medical institute and accidentally meets a girl called Gerda along with her hippie friends.
Sasha learns to drink wine from the bottle and suffers from the alienation of Sun, who’s constantly absent.
In Crimea, hippies stop in a rented house, go to improvised discos and dance to rock music, which is broadcast on the pirate radio by a mysterious "Trouble Woman" (as it turns out, the daughter of the chief in the local militsiya).
Here it turns out that Sun is terminally ill and needs urgent treatment in Moscow.
Then he turns to the "Trouble Woman", who gives him the money to bribe her mother — militsiya officer.
