Four girls, Patti (Lili Taylor), Emma (Anna Grace), Angela (Bruklin Harris), and Nicki (Aunjanue Ellis) are completing their last year of high school. Unfortunately for the group, one of their own, Nicki, unexpectedly commits suicide. The three remaining girls, upon finding out that Nicki had been raped before she died, begin to talk to each other about the ways in which they are oppressed by the men in their lives. They begin to fight together, taking revenge on Emma's rapist, Patti's abusive ex-boyfriend, and finally, Nicki's rapist.
