Waterloo will now have its own semi-pro men's hockey team, thus expelling the amateur women's leagues from the arena. To avenge their lost ice time, an impulsive hockey player and a ruthless octogenarian—a former derby champion—have a plan: recruit the city's disenfranchised and form an underground roller derby team. With the help of the Women's Club, they will prove that women's sports can also inspire crowds and that sisterhood is the ultimate act of resistance.

Marie Lamontagne, a widowed mother of two in her forties, confesses to a murder she didn't commit to protect her daughter. Thrust into brutally unfamiliar and hostile surroundings, she first learns survival, then confronts the biggest challenge of her life: bonding with her fellow inmates and helping them take back control of their lives.
