Born in the 1930s, Roller Derby has enjoyed a resurgence since 2002. Several leagues have been formed, most of them for women only, whose sexy costumes emphasising their femininity formed a stark contrast with the roughness of the sport. Players assume alter egos with names like Patsy Crime, Dolly le Dukes, Tawdry Hepburn or Death by Chocolate. Shelley Calton vividly depicts the tempo and emotions of the game, exploring how the players' image demands both a typically masculine attitude and an erotic showcasing of their bodies.
