Dana Diaz is an aspiring stand‑up comedian—a woman in a man’s world. When she meets a tough computer programmer named Amanda Dorn, the two bond over their struggles in boys’ club professions. Dana confides that she’s recently been harassed and assaulted while in L.A., and Amanda comes up with a plan: they should go after each other’s assailants, Strangers on a Train–style. But Dana finds that revenge, however sweet, draws her into a more complicated series of betrayals. Soon her distrust turns to paranoia, encompassing strangers, friends—and even herself.
