The film follows Jonathan E. (James Caan), the veteran star of the Houston rollerball team. By virtue of his stellar performance over the years, Jonathan has become the most recognizable Rollerballer in history; everyone recognizes him on sight. This is problematic for the hegemonic corporations. After another impressive performance in Houston's victory over the Madrid team, Energy Corporation chairman Mr. Bartholomew (John Houseman) announces that the corporation, running out of ways to reward its champion, will feature Jonathan in a "multivision" special devoted to his career.
Bliss Cavendar (Ellen Page) is a misfit in the small town of Bodeen, Texas, with no sense of direction in her life. Her mother, Brooke (Marcia Gay Harden), a former beauty queen, pushes her to enter beauty pageants despite her lack of interest. During a shopping trip to Austin with her mother, Bliss encounters three roller derby team members and finds herself intrigued by the sport in which teams and players are given pun names that highlight the violent aspect of the sport. Intrigued, she and her friend Pash attend a roller derby bout under the pretense of going to a football game, where they see the "Holy Rollers" defeat the "Hurl Scouts", a perennially unsuccessful derby team.
