An idealistic FBI agent (Emily Blunt) is assigned to work a dangerous stretch of the US-Mexico border by her superior officer (Josh Brolin). She's exposed to the brutality of the Mexican drug cartel, and becomes partners with a defector from the cartel (Benicio Del Toro) who possesses keen knowledge about the organization. As she gets deeper into the ruthlessness and corruption surrounding the FBI sting to find the organizations leaders, her moral and professional boundaries are pushed to their breaking point. Denis Villeneuve directs this pulse-pounding crime drama, which competed for the Palme d'Or at the 2015 Cannes Film Festival.
