The story, like McCarthy’s No Country for Old Men, is set along the Mexican border. It centers on an attorney (Fassbender), a good man in need of money, who decides to dabble in the cocaine trade. He teams up with a rich acquaintance (Bardem) for a new business that also brings in a shady type (Pitt). Things don’t go as planned, in what is described as a dialogue-heavy, violent and racy script.

Nick Wechsler and Paula Mae Schwartz are producing.
