Raina Petree is crushing her senior year, until her boyfriend dumps her, the drama club (basically) dumps her, the college of her dreams slips away, and her arch-nemesis triumphs.

Things aren't much better for Millie Goodwin. Her father treats her like a servant, and the all-boy Mock Trial team votes her out, even after she spent the last three years helping to build its success.

But then - an advice columnist unexpectedly helps Raina find new purpose in a pair of knitting needles and a politically active local yarn store. This leads to an unlikely meeting in the girls bathroom, where Raina inspires Millie to start a rival team. The two join together and recruit four other angry girls to not only take on Mock Trial, but to smash the patriarchy in the process.
