Small town Texas has become a bore and Bliss Cavendar (Ellen Page) plans to escape her boredom. Her parents Earl (Daniel Stern) and Brooke (Marcia Gray Harden) are wrapped up in their football and beauty pageants. Bliss shares her plan with her best friend Pash (Alia Shawkat). Pash has been applying to Ivy League schools but Bliss needs away to get out. She picks up a flyer at the mall that advertises the Roller Derby. Bliss is invited to try out and makes the team after lying about her age. She is known now as Babe Ruthless on the tour and experiences things she never thought possible. Her parents are not thrilled with her pursuit of her derby fame and try to stop her.
