A deadly strain of flu mutates, causing the deaths of millions throughout Ireland and beyond. But the infected don’t stay dead for long, rising up to become flesh-eating monsters. 

Geri McConnell is a survivor. Through the graffiti-stained streets of Belfast she runs, determined to stay one step ahead of the ever-increasing hordes of living dead. 

In neighboring Finaghy, God-fearing Karen looks to the stoic and level-headed Pat Flynn for a paternal figure. But with a checkered past as an IRA gunrunner, Pat is battling demons of his own.

Meanwhile what remains of the military congregate in a run-down base thirty miles south of Belfast.

And the virus is airborne. Anyone can become infected.

Flu is a terrifying and brutally realistic zombie horror story.
