Marina has been doing gymnastics for over 15 years. She is the oldest gymnast of the Zhemchuzhina Olympic Reserve School. She would be happy to end her career and live normally, study, have a hobby, love. But at the behest of the coach, she did not go to the competitions that she had been striving for her entire career. Therefore, at the age of 20, she is forced to stay in the sport for another two years in order to wait for the next chance, and her coach is forced to undergo endless trials, because that very prison of Marina is the life of Elena Anatolyevna.
