There's a nasty flu going round. An epidemic, they call it. The posters say to cover your mouth when you sneeze, and throw away the tissue. But such simple measures won't stop this flu. Because when you catch the flu, armed police come and lock you in your house to die alone. When you catch this flu, it kills you in days. And when you catch this flu, two hours after it's killed you, your eyelids snap open again . . . Flu is a pacey, terrifying, frighteningly real zombie horror story.
