An exhilarating mix of dark comedy, white-knuckle action and dramatic intrigue, “Gringo” joyrides into Mexico, where mild-mannered businessman Harold Soyinka (David Oyelowo) finds himself at the mercy of his back-stabbing business colleagues back home, local drug lords and a morally conflicted black-ops mercenary. Crossing the line from law-abiding citizen to wanted criminal, Harold battles to survive his increasingly dangerous situation in ways that raise the question: Is he out of his depth – or two steps ahead?
