Rachel feels like she doesn't fit in - until she finds heavy metal music, that is. Life gets even better when she meets Fern, a kindred spirit. Together they form their own band, but the metal scene turns out to be no different than the misogynist world they have wanted to change all along. After a violent encounter escalates, the friends decide there's only one way forward, to wreak violent revenge. A blood-stained journey into the dark heart of the music industry, Boring Girls, traces Rachel's deadly coming of age, Fern at her side.
