In search of answers to the tragic disappearance of her husband, a biologist volunteers for an expedition in an area closed by the government over the past 30 years as an ecological disaster area. A secret agency, known as the Southern Reach, sent people into 11 expeditions during those years to discover the truth about the X zone, but those attempts have resulted in failures.
When the young biologist and her team embark on a dangerous expedition to the mysterious X zone, they find an untouched wild nature, but they also quickly see that the rules of nature and evolution seem to work a little differently. In the midst of the wild wilderness that does not adhere to the laws of nature, they discover an unusual and dangerous creature. How will their risky mission end?
