“Boyka: Undisputed V” (2025) brings back the legendary Yuri Boyka, the undisputed king of underground fighting, now striving to leave his violent past behind. After the events of the fourth film, Boyka has been living a quiet life, working in a small gym and helping underprivileged youth stay off the streets. However, his peaceful days are shattered when a ruthless crime syndicate expands its illegal fighting circuit across Eastern Europe, forcing fighters into brutal, life-threatening matches for the entertainment of wealthy gamblers.

When Boyka learns that one of his former protégés has been killed in the ring, he is pulled back into the underground world he swore to leave. Driven by guilt and a sense of unfinished business, Boyka challenges the syndicate’s top fighters, aiming to dismantle their operation from within. But the deeper he goes, the more he realizes this is not just a fight for survival, but a battle against a powerful organization that thrives on corruption and exploitation.

As Boyka rises through the brutal tournament ranks, he crosses paths with new allies, including a fearless female fighter named Katya, who is fighting to free her kidnapped brother. Together, they expose the dark underbelly of the syndicate’s network, revealing how it controls fighters through threats, debts, and violence. Meanwhile, the syndicate’s reigning champion, a towering beast of a man known as Viktor Dragunov, awaits Boyka at the top — a fighter with a personal vendetta against him.

The film builds towards an electrifying climax as Boyka confronts Dragunov in a no-rules fight, staged in an underground arena packed with ruthless spectators. Every punch, kick, and takedown is a brutal reminder of Boyka’s past sins and his relentless pursuit of redemption. But beyond the physical fight, Boyka must overcome his own demons — the guilt, anger, and loneliness that have haunted him for years.

In the end, “Boyka: Undisputed V” is more than just a story of bone-crushing fights; it is about honor, redemption, and the fight for one’s soul in a world where violence often seems like the only answer. As Boyka stands victorious, bloodied but unbroken, he finally understands that being the most complete fighter is not about winning in the ring, but about fighting for something greater than himself.
