Years after his last fight, Yuri Boyka (Scott Adkins) is living a quiet life, training young fighters and seeking redemption for the violence of his past. But when a ruthless underground fight promoter (Michael Jai White) forces Boyka’s protégé into a deadly match, Boyka is dragged back into the brutal world he swore to leave behind. To save the kid — and his soul — Boyka must step back into the cage for a global tournament unlike anything he’s faced before, where the rules are simple: fight, win, or die.

Across continents, Boyka faces deadly opponents — including a silent assassin (Iko Uwais) and a vengeful ex-soldier — while confronting his own inner demons. As the stakes rise, he learns that the greatest battle isn’t in the ring, but within himself. With bone-crushing fights and explosive choreography, Boyka: Undisputed 5 delivers raw emotion, unstoppable power, and the ultimate test of honor.
