Signs meets 10 Cloverfield Lane in this terrifying alien invasion horror based on events experienced by a real American family in 1955. A young boy’s thirteenth birthday party on his family’s isolated farm is interrupted by the arrival of extraterrestrials and their flying saucer. At first, the boy’s family believes their son’s sighting is nothing more than one of his tall tales, but as the night drags on it becomes clear they are not alone on their little farm, or in the universe. The little grey aliens may look small, but when their actions reveal them as hostile, and the bullets from the family’s guns prove powerless, what began as a celebration of life becomes a bitter fight to the death. Miles from the nearest town, and with the phone lines cut, the family must use everything at their disposal to keep from becoming the next subjects of their new visitors' horrible experiments.
