A tense second trailer has debuted for "Sicario," the new crime drama from "Prisoners" director Denis Villeneuve.

The film stars Emily Blunt as idealistic FBI Agent Kate Macy, who's recruited by a CIA official (Josh Brolin) to aid in the escalating war against drugs. Joining an elite government task force that’s led on a clandestine journey into Mexico by an enigmatic consultant with a questionable past (Benicio Del Toro), Kate is forced to question everything she believes in order to survive.

Opening Sept. 18, “Sciario” also stars Jon Bernthal, Daniel Kaluuya, Maximiliano Hernández and Jeffrey Donovan.
