Polar Inertia - Parallel Transport (Rollerball 1975)

In 2018, Jonathan E. is the team captain and veteran star of the Houston Rollerball team. Mr. Bartholomew, chairman of the Energy Corporation and team sponsor, offers Jonathan a lavish retirement package if Jonathan will announce his retirement during a upcoming television special detailing his career. Jonathan refuses, and requests to see his former wife Ella, who had been taken from him some years earlier by a corporate executive who wanted her for himself.

Jonathan goes to a library, where he finds that all books have been digitized and edited to suit the corporations, and are now stored on supercomputers at large protected corporate locations. Jonathan's friend Cletus warns him that the Executive Committee is afraid of him, though he cannot find out why.

Rollerball soon degrades into senseless violence as the rules are changed just to force Jonathan out. The brutality of the match kills several players and leaves Jonathan's best friend and teammate Moonpie in a coma.

In a teleconference, the Executive Committee decides that the next game will be played with no penalties, no substitutions, and no time limit in the hope that Jonathan will be killed during the game. Jonathan's popularity and longevity as a player threaten the underlying agenda of Rollerball: to demonstrate the futility of individualism.

Jonathan makes his way to Geneva to access the world's repository of all human knowledge, a central supercomputer known as "Zero," only to find its memory corrupted. Afterwards, Jonathan receives a visit from his former wife Ella, who has been sent to convince him to retire and to make it clear that the coming game will be "to the death." Jonathan realizes his wife's visit was set up by the Executives, and erases a long-cherished movie of the two of them, stating, "I just wanted you on my side." Jonathan decides that despite the dangers, he will play.

The final match devolves into a gladiatorial fight. Jonathan is soon the only player left on the track for Houston, while a skater and a biker remain from New York. After a violent struggle in front of Mr. Bartholomew's box, Jonathan kills the skater and pins the biker down and raises the ball over his head, then pauses. Refusing to kill his fallen opponent, Jonathan gets to his feet and makes his way to the goal, slamming the ball home and scoring the game's only point. After a bloody match which sees all of his teammates killed, Jonathan takes a victory lap as the crowd chants his name.
