Boyka: Undisputed IV 2016

Months after the events of the previous film, Yuri Boyka is a free man who still fights in Kyiv’s underground arenas, guided by a manager Kiril. His latest bout ends in tragedy when he accidentally kills Viktor Emilien De Falco, a moment that haunts him and makes him question what he is truly fighting for. Learning that Viktor leaves behind a wife named Alma, Boyka resolves to help her, even if it means stepping into a dangerous game far from home. He tells his manager to arrange a fake passport and heads to Russia to confront the debt shadowing Alma.

In the Russian town of Drovny, Boyka discovers that Alma owes money to a feared crime boss, Zourab. Alma lives in a community center and works as a waitress in Zourab’s underground fighting club, a place where violence is currency and loyalty is earned through strength. Zourab is eager to recruit a top martial artist for his club, and Boyka, desperate to free Alma from her burden, proposes a deal: he will fight for Zourab in three matches in exchange for Alma’s freedom. The offer is risky, but Alma’s plight leaves him little choice, and she invites him to the training room in the community center to prepare.

The first match is a swift demonstration of Boyka’s skill, as he defeats his unnamed opponent with controlled precision and resolve. In the second bout, he faces two brothers and defeats them with a hard-witted combination that ends in a double knockout, proving his unmatched discipline and power. Through the training, Alma explains why she cannot leave the town—her children need stability, and the center is the only home they’ve ever known, a sentiment that deepens Boyka’s resolve to see her free.

For the third match, Boyka confronts Igor Kazmir, the elite henchman of Zourab. The fight is grueling, but Boyka prevails, proving he can overcome even a fiercely trained enforcer. Yet Zourab refuses to stop there and bribes a high-ranking police officer to bring in his secret, devastating stronger fighter: Koshmar. Koshmar is a giant, furious, and relentless martial artist whose presence unsettles the arena and tests Boyka’s limits.

The battle with Koshmar pushes Boyka to the edge. After a brutal exchange, he manages to break one arm and one leg of the towering foe and finally knocks him unconscious, denying Zourab the chance to claim an easy victory. Enraged by the defeat, Zourab takes Alma hostage and orders his henchmen to kill Boyka. In a brutal confrontation, Boyka overcomes the onslaught, shoots is avoided, and ultimately chokes Zourab to death, protecting Alma even as he is wounded.

Arrested and taken away, Boyka spends time in prison, where he wrestles with his own guilt and the price of redemption. Six months later, Alma visits him in prison and tells him that she has forgiven him for Viktor’s death. The encounter rekindles Boyka’s determination, and he continues to fight within the prison walls, chasing the ideal of becoming the world’s most complete martial artist.

In the end, the story remains a rigorous test of character, showing that strength without purpose can lead to tragedy, but a fighter with resolve can still choose a path toward forgiveness, responsibility, and a more honorable form of mastery.
