In the year 2018 violence has been outlawed and corporations have replaced government as the ruling party following the demise of politics. With the absence of war or conflict, a forcibly passive population's bloodlust is satisfied by a brutal new sport known as Rollerball. A high-octane melding of the outlawed sports of the past, the worldwide phenomenon of Rollerball has resulted in a corporate-backed sensation. The most popular athlete in the world, Jonathan E. (James Caan) has steadily risen through the ranks to become a legendary veteran of the sport. When the corporate backers of Rollerball begin to fear that Jonathan's popularity has instilled him with a potentially dangerous amount of power, a thunderous struggle between man's free will and the oppression of the masses threatens to shatter the fragile strings that the puppet masters use to manipulate mankind. His determination to remain with the sport flying in the face of the very reason Rollerball was conceived, the corporate rulers hatch a plot to abandon the rules in hopes that Jonathan will be killed and their grip of power will remain an unyielding chokehold on an increasingly bloodthirsty populace.
