Output: After returning home from South Korea, three members of the U.S. National Karate Team set up a martial arts studio in Las Vegas. Travis has been secretly competing at The Coliseum, a brutal underground fighting arena run by Weldon, whose protege Brakus is the owner and undefeated champion. Ordinarily a challenger must defeat three of its Gladiators in order to face Brakus, but Travis challenges Brakus outright. Amused by Traviss arrogance, Weldon grants his wish. Alexs elevenyearold son Walter begins testing for his black belt, but falls short. When his father makes an impassioned speech praising his son for his maturity, Walter cancels his babysitter. Alex insists that Walter accompany Travis to his bowling league. Travis reveals his secret to Walter, who blackmails Travis into letting him watch the fight with Brakus. Brakus pummels Travis and breaks his neck, killing him. Walter runs home and alerts his father and Tommy, and together they proceed to the dance club which serves as a front for the Coliseum. They are intercepted by Weldon, who claims that Travis left the Coliseum on his own. Tommy searches the city until the police find Traviss body floating in the river along with his damaged car, the apparent result of an auto accident. Alex and Tommy return to the club and confront Brakus, who admits to killing Travis. Tommy connects with a punch that sends Brakus crashing into a mirror, scarring his cheek. Brakus condemns Alex and his son to death, but orders Weldons henchmen to bring Tommy back alive. At Traviss funeral, Alex and Tommy are startled by the appearance of Dae Han, Tommys old rival from South Korea, and adopted brother. Still owing a debt to Tommy for sparing his life, Dae Han pledges to help his friends and his brother bring Traviss killer to justice, which Tommy politely declines. While riding his bike home from school, Walter is tailed by a black vehicle. He returns home to warn his father and Tommy, but they come under attack by a group of armed men. After fending them off, they pack up and head out of town to seek refuge with Tommys Native American grandmother. There they encounter Tommys uncle James, a oncepromising fighter whose career was ruined due to a clash with Brakus. Claiming to know how to defeat him, James begins to train Alex and Tommy. Their training does not last long as Weldons henchmen track them down. James tries to intervene but is shot to death. While Tommy is forced into the waiting helicopter, Alex and the others are herded back into the house. As Weldons men prepare to execute them and blow up the house, Walter provides a distraction which enables Alex to overpower the gunman. Tommys grandmother prompts Alex to fire four shots to signal their deaths, at which point the thugs set fire to the gasoline trail, causing a massive explosion. After emerging from the cellar unharmed, Alex leaves Walter with his girlfriend Sue, then recruits Dae Han and his Korean teammates to storm the Coliseum and rescue Tommy. At the Coliseum, Tommy fights his way through the Gladiators, but is outmatched by Brakus. As Brakus prepares to finish him, Alex breaks into the arena, his presence giving Tommy a second wind. A barrage of kicks send Brakus to the canvas, and Tommy warns him to stay down. But Brakus does not comply, leaving Tommy no choice but to break his neck. With his champion defeated, Weldon announces Tommy as the new owner of the Coliseum and invites him to say a few words to the audience. Tommy takes the microphone and declares the Coliseum closed. When Weldon protests, Alex silences him with an elbow to the face. Alex and Tommy leave the arena and turn off the lights.
