Rory is a nurse at her wit's end. After losing all but one of her cancer riddled children, she has to make the devastating decision to either leave the sanctuary of the hospital in search of better supplies... or staying. Food runs out and the radio keeps screeching of shelter; she has to help the child and herself survive. Being locked in the hospital for several months, she doesn't know of the mutations and horrors that wait for them on the outside. She has to fight. She has to learn. She has to sacrifice her safety for the safety of another. But most importantly, she has to survive.
