The Strain (2014)

During the American Civil War (1861-1865), four men and a young boy flee aboard a balloon. A hurricane makes them run aground on a totally unknown volcanic island, far from any civilization. They must learn to live like Robinson Crusoe, tame a particularly hostile flora and fauna and even resist a pirate attack. But an invisible hand watches over our heroes and lets them predict that they are not alone on this truly mysterious island.
