Boyka: Undisputed is a 2016 martial arts film and is the sequel to the 2010 boxing film Undisputed III: Redemption. Scott Adkins reprises his role as Yuri Boyka. Tim Man, who choreographed the action for Adkins in Florentine’s Ninja: Shadow of a Tear, serves as the film’s fight choreographer.
In the fourth installment of the fighting franchise, Yuri Boyka is shooting for the big leagues when an accidental death in the ring makes him question everything he stands for. When he finds out the wife of the man he accidentally killed is in trouble, Boyka offers to fight in a series of impossible battles to free her from a life of servitude.
