Harold Soyinka (David Oyelowo) is a smart, but naïve man, born in Nigeria. He is the Operations Manager for a pharmaceutical company with facilities in several countries, including Mexico. He believes his boss – Richard Rusk – is his friend, until he learns that the company is about to go public, and he will probably be fired. In debt way over his head and married to a woman (Thandie Newton) who tells him she wants a divorce on Skype while he’s in Mexico, Harold becomes desperate. 
Elaine Markinson (Charlize Theron), diabolical business partner of duplicitous Richard Rusk (Joel Edgerton), knows exactly how to get a rise out of the men she works with. Foul mouthed, gorgeously sexy, shrewd, and self-centered, she provided most of the belly laughs in this dark comedy.
Without giving away the story, which involves vicious Mexican drug lords, a morally-conflicted black-ops mercenary, the DEA, two young Americans, and quick-to-learn Harold Soyinka who ends up on the run from the above, GRINGO is fast-paced, exciting, full of twists and turns, satisfying ending, convincing actors and great entertainment. Totally enjoyable.
