A prisoner escapes from jail and robs and kills a man. CID is called to the scene to begin searching for the man. But a seemingly ordinary case goes awry when a deformity on the victim's body, first thought to be cause by acid burns at the hands of the prisoner, turns out to be the result of a virus- that the prisoner is now carrying around the city, possibly infecting hundreds. Can CID catch the prisoner and stop this calamity?
