I find myself increasingly hoping that any potential discovery of life beyond Earth doesn't come from the United States! Here, NASA dispatches a probe to gather information about something they believe could be valuable in space, but they botch the spacecraft’s return, turning large portions of Mexico into a restricted zone. Across the border from this secured area is seasoned photographer “Kaulder” (Scoot McNairy), who instead of obtaining pictures explaining the heightened security measures, finds himself responsible for “Sam” (Whitney Able), the daughter of his American employer. With essential services broken down and residents struggling to survive, getting them back home will be challenging – particularly given rising costs and his fondness for prostitutes and being robbed. It’s this last habit that lands them in the care of human traffickers and local tribespeople who occasionally seem quite superstitious—but will they succeed? To begin with, there aren't really any creatures to speak of here, and it unfolds at a deliberate speed, so if you’re anticipating an alien spin on “Jurassic Park,” this isn't going to satisfy. What the film does achieve, considering its apparent low budget, is presenting us with several well-shot and dangerous situations utilizing the jungle, waterways, shady individuals, and a commendable sound design that builds a noticeable atmosphere of dread. There’s a good rapport between Able and McNairy; frankly, if I were in her position, I probably would have abandoned “Kaulder” to the crocodiles on numerous occasions! It's true that the story loses momentum, and the final twenty minutes aren't particularly memorable, but if you allow your own imagination to work with director Gareth Edwards’ vision and overlook some of the unremarkable lines, then it’s a reasonably entertaining thriller worth seeing.
