Twenty-six year-old Taylor Martin is a nurse working at an inner city hospital. An energetic, strong and independent young woman, Taylor sees it as her mission in life to cure the world of its troubles - beginning by convincing her friend, Holly, to give up smoking.
But a normal day at work turns into a nightmare for the two friends when they're sent to the site of an incident in the city centre. They arrive on the scene to find a military-controlled quarantine surrounding a group of office buildings. Information is being kept tightly under wraps, but Taylor and Holly are instructed to treat the victims of a rampant and unknown virus. The terrifying illness strips the flesh from its victims, driving them insane before finally killing them.
