Young boxer Arlan, a trainee at the Olympic Reserve Boxing School, dreams of making it to the Olympics. However, he is forced to take on side jobs to support his mother and younger brother, who suffers from a rare illness. One day, while working at a store, he meets Alina, a piano student at the conservatory who secretly dreams of becoming a singer. Their meeting inspires her to gain the confidence to choose her own path. As his brother’s condition worsens and expensive treatment becomes necessary, Arlan, following the advice of his friend Tokha, agrees to take part in underground bare-knuckle fights to earn quick money — sacrificing his dream of Olympic gold. Now, he must endure a grueling journey through the brutal world of underground fighting, where the reigning champion is the undefeated Nikita Aday.
