When an alien spaceship crashes in rural farmland in England, it presents one-in-a-lifetime opportunity to explore the unknown and discover one of the greatest mysteries in history of humankind.

Someone else beat them to it and, before anyone suspects anything, it's already too late. Not everything is as it seems and a mysterious illness spreads throughout the village, infecting indiscriminately, and threatens to take over.

Will the country's greatest minds be able to find a cure before the entire village succumbs and the infection spreads further?
