When an accident leads to a new and deadly virus leaking from a biological weapons facility, it doesn't take long for the virulent strain to spread and start taking effect on those it encounters. The first effects are flu-like and seem innocuous enough, but this quickly evaporates, leaving the infected with feelings of murderous rage before they are finally overwhelmed and transformed into blood-crazed and mindless zombies. With mankind on the brink of total annihilation a new hope arrives. Derrial is a servant of God, sent by Him to Earth to form an army from the surviving Christians, in the hope that they can stem the tide of death. But for every servant of good there is also a servant of evil and this comes in the form of Landus, the devil himself, disguised as a biker gang leader. Landus sets about recruiting the surviving sinners to his malevolent cause, and with them and a gathering horde of zombies at his command it looks like the end for civilization. But as they descend on what's left of Chicago, Derrial gathers his remaining followers for one last stand between good and evil. Will humanity survive, or is it already too late?
