BAFTA Award nominated Gemma Arterton (Quantum of Solace, Clash of the Titans) and Academy Award nominated Glenn Close (Guardians of the Galaxy, Fatal Attraction) star in this post-apocalyptic horror which critics have called 'the best zombie movie since 28 Days Later’. In a heavily guarded compound, a small group of children are being studied to discover the cure to a virus that has ravaged the globe. 10-year-old Melanie (Sennia Nanua) and her fellow pupils are second-generation hybrids - part 'Hungry’, part human. But unlike first generation 'Hungries’, Melanie excels in the classroom, is acutely attentive, imaginative and highly intelligent. When the base is overrun by Hungries, Melanie escapes with her favourite teacher, Miss Justineau (Gemma Arterton), Sergeant Parks (Paddy Considine) and Dr. Caldwell, who is intent on using Melanie to synthesize a vaccine. Bound for a fortress-like enclave where society clings to life, can they survive? Does Melanie hold the key to unlocking a cure for the plague on course to destroy the human race?
