SEMIANIMUS

 

 It had just seemed like a bad dose of flu at the time. People went to doctors and chemists. They took time off work and rested. They felt fine after a few days. A few weeks later, they had forgotten all about it.....

A hot Sunday morning. Ireland is bathed in sunshine. The sickness returns, but much worse. Those afflicted crave human flesh. Within hours, the country is in turmoil. 
A group of survivors barricade themselves inside their house. After a while they feel safe. They let their guard down. This allows in a threat that is every bit as dangerous as the undead hordes that roam the streets outside.
