Along the way to a conclusive shootout that seems to reap as many casualties as a small-scale military operation, Wooters secretly romances – and straightforwardly seduces – Cohen’s good-hearted moll Grace Faraday (Emma Stone).

O’Mara and company occasionally express second thoughts about their methods. But screenwriter Will Beall’s script, adapted from Paul Lieberman’s eponymous book, presents their illegal actions as the only practical solution open to them.

Given Cohen’s ruthlessness – he eventually orders a machine-gun attack on O’Mara’s home, endangering the upright sergeant’s pregnant wife, Connie (Mireille Enos) – the audience is invited to react as viscerally as the characters to his seemingly unstoppable reign of terror. Moviegoers will require maturity and prudence to work through the tangled ethics of the situation – and a strong stomach to endure the wild gunplay and interludes of brutality.

The film contains a vigilantism theme, scenes of gruesome, bloody violence, a premarital situation, brief partial nudity, numerous uses of profanity and much rough and crude language. The Catholic News Service classification is L – limited adult audience, films whose problematic content many adults would find troubling. The Motion Picture Association of America rating is R – restricted. Under 17 requires accompanying parent or adult guardian.
