After a zombie apocalypse has almost destroyed civilisation as we know it, three groups of survivors find themselves holed up in an underground military base. The scientists had been ordered to study the undead, the soldiers ordered to protect the scientists, and the remaining civilians ordered to help in any way they can. But with no more input from a government who may not be around anymore, the three distinct groups slowly find temptation in abondoning their tasks and living out their last days in a way more of their choosing - leading to major conflict between the survivors.
