A neurological pandemic has consumed the population. Drug-resistance has mutated the virus into a ravaging psychological plague, rendering the 'the dying' desperate, paranoid and violent. Two survivors come together on an isolated farmhouse in desperate circumstances- April, a young mysterious girl with a dark past has survived alone for months, and Daniel, a man desperate and bereaved, clings desperately onto hope in the outside world. When a mysterious stranger turns up, they are confronted with a new enemy even deadlier than the one beyond the perimeter.
