Waterloo will now have its own semi-pro mens hockey team, thus expelling the amateur womens 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 citys disenfranchised and form an underground roller derby team. With the help of the Womens Club, they will prove that womens sports can also inspire crowds and that sisterhood is the ultimate act of resistance.
