After his release from prison Nick Roest, a former K1 champion, is eager to make his comeback. He landed in jail after a serious violent crime, which involved his young (half) brother David Roest. The brothers have a complicated love-hate relationship, a relationship shaped by the Spartan upbringing by their dominant father, the legendary kickboxing trainer John Roest. Roest is the man who made kickboxing big in Holland. Nick is determined to give it his best to fight his way back to the top. To accomplish his goal he will have to get in good graces with his father again. Roest, however, it is not planning on easily forgiving Nick for his sudden switch to a rival trainer. It turns out that the up and coming fighter Jerry has taken Nick’s place at the gym. Jerry is clearly the one who will take over from Roest. Jerry is a boxer with the appearance of the ideal sonin- law. Before Nick went to prison he was on the fast track to becoming famous. So the day Nick knocks on the door of the gym, is the day John Roest has secretly been hoping for. When he suffers a stroke he knows his end is approaching. Just then Jerry’s clean image is starting to show signs of cracking. The old fighter has to decide who of the two should inherit what he has built.
