From director Denis Villeneuve comes a searing, emotionally-charged thriller that takes you on a terrifying descent into the heart of the drug wars raging in the lawless borderlands between the United States and Mexico--a blood-stained land of chaos, corruption, brutality and moral mayhem.

When Arizona FBI agent and kidnap-response-team Leader Kate Macer (Emily Blunt) uncovers a Mexican cartel's house of death, her shocking find leads to profound consequences on both a personal and global level. Kate is recruited to join a covert black-ops mission headed by a mysterious Colombian operative known only as Alejandro (Benicio Del Toro) along with special agent Matt Graver (Josh Brolin). Even as Kate tries to convince herself she's on a hunt for justice, she is thrust into the dark heart of a secret battleground that has swept up ruthless cartels, kill-crazy assassins, clandestine American spies and thousands of innocents.
