Sennia Nanua, Gemma Arterton and Glenn Close star in this sci-fi drama based on M.R. Carey's novel. In a post-apocalyptic future, humanity has been devastated by a mutated fungal disease that has turned most of the Earth's population into ravenous zombies, known as 'hungries'. In a secure army base in Birmingham, a group of scientists experiment on part-human, part-hungry, hybrid children in the hope of finding a possible cure to the epidemic. In this fortified facility, teacher Helen Justineau (Arterton) believes ten-year-old Melanie (Nanua) may hold the answers to a future cure but objects to her superior, Dr. Caroline Caldwell (Close)'s plan to kill her for further experimentation. When the survivors find their base under attack from hungries they are forced to flee to England's destroyed capital where they continue their fight for survival and for a better future.
