In 2005, the new sport of Rollerball, an extraordinarily violent extension of roller derby involving motorcycles and a metal ball, becomes hugely popular in many countries. Marcus Ridley (LL Cool J) invites NHL hopeful Jonathan Cross (Chris Klein) to join him playing for the Zhambel Horsemen in Kazakhstan. The highly paid Marcus and Jonathan are teamed with low-paid locals, who are often severely injured in the game. In the beginning, Jonathan, the team's star player and the poster child of promoter Alexi Petrovich (Jean Reno), is enamored by the high-octane sport, the popularity, sports cars, and his female teammate Aurora (Rebecca Romijn). But Jonathan and Ridley eventually discover that the cynical Alexi and his opportunistic assistant, Sanjay (Naveen Andrews), have a vested interest in keeping the game as popular as possible, through planned gory "accidents" and ensuring that Jonathan and Ridley cannot quit the team and remain high-profile stars. After an accident almost kills Aurora, Jonathan and Ridley decide that they need to flee the country to save their lives. The two are followed by Alexi and several bodyguards, who attack the two before they can reach the Russian border. Jonathan is injured and Ridley has to leave him behind. Alexi and his men capture Jonathan and kill Ridley after the latter successfully crosses the border. Following the escape attempt, Alexi tries to stage a public execution of Jonathan by removing all the rules from the upcoming Rollerball match, along with trading Aurora to the opposing team (as requested by Jonathan in an attempt to get her away from danger). However, Jonathan, with the help of his teammates, start a revolution, causing the fans to see the sport for what it really is, and ultimately to kill Alexi.
