Living in small town Bodeen Texas, seventeen year old Bliss Cavendar, who works part-time at the Oink Joint diner with her best friend Pash while they finish school, is always in quiet rebellion against her mother, Brooke Cavendar, a former beauty queen about her making the unilateral decision to enter both Bliss and Bliss' adolescent sister Shania in beauty pageants. Brooke, a postal worker, is exactly as she wishes her mother was, in wanting her to have taken control of her pageant life as a stepping stone to bigger and better things in life. Conversely, Bliss sees beauty pageants as an outdated expression of female empowerment. Bliss knows she will not get any support from her father, Earl Cavendar, in her battles against her mother, as Brooke wears the proverbial pants in the family. Bliss stumbles onto the world of the five team Texas Roller Derby League based in Austin, she intrigued upon first seeing the league's flyer. Despite knowing nothing about roller derby, Bliss is encouraged to try-out by the captain of the Hurl Scouts, Maggie Mayhem. Finding that she's found something of passion for her life, Bliss trains and tries-out, she making the team displaying natural skating speed most suited to the position of jammer. As she doesn't have the natural aggression to check, she decides to don the stage name Babe Ruthless. The Hurl Scouts, who become Bliss' second family, see the sport solely as fun, and never really listening to their coach Razor, they have perpetually finished last in the league, never winning a bout. Regardless, Bliss catches the eye of Iron Maven, the star jammer of the undefeated Holy Rollers, she seeing in Bliss a potential threat to her star jammer status. Bliss decides to hide her roller derby life from her family while she tries to balance this new passion against respecting the fact that her parents are her parents who are only looking out for her best interest. That new life includes a relationship with a musician named Oliver, whose rock band often attends roller events.
