在这部区剧情片中,《Zona》小说原作叫《路边野餐》（国内出过中译本），曾在2012年被芬兰改编成电影，叫做《Vyöhyke》，故事讲述1986年4月27日，一艘巨大的不明飞行物体在芬兰南部坠毁，这次事故甚至改变了那片地区的自然法则，从而形成了巨大的危险地区。这是全球6个类似的区域之一，并且是同时在一天之内形成，后来被称为“区域”（Zones）。芬兰的防卫军以及其他的官方警力介入也全部无功而返，行动中还有数百士兵和平民或死或失踪。而当地的原住民也再也找不着了。军方只能把这片区域给封锁起来，日夜看守，让它与外界隔绝，不让任何人员进出。（文/時代映畫社）
April 27th 1986 An unidentified flying object crashed down in the southern region near Linnakallio village, resulting in the forming of an hazardous area, where the laws of nature have gone askew. This was one of the six regions, that were formed within a day in the Northern Eurasian and Northern American area. These regions were later known as "Zones". The joint efforts of Finnish Defence Forces and other authorities in evacuating the area ended in total failure. Hundreds of soldiers and civilians either died or disappeared during the operation. The original inhabitants of the affected area were never found. The military isolated the zone completely from the outside world. Posting fences, guard towers and guarding the area day and night, the soldiers effectively blocked anyone from getting into the zone, or out from there. Or so they thought.
