A typist in a New York City Police Department precinct, Rose is like a high priestess. Confessions are her job. It is 1923, and while she may hear every detail about shootings, knifings, and murders, as soon as she leaves the interrogation room she is once again the weaker sex, best suited for filing and making coffee.

When glamorous Odalie, a new girl, joins the typing pool, despite her best intentions Rose falls under Odalie's spell. As the two women navigate between the sparkling underworld of speakeasies by night and their work at the station by day, Rose is drawn fully into Odalie's high-stakes world. And soon her fascination with Odalie turns into an obsession from which she may never recover.
