Boston 1974.A man out for revenge and utilizing a deadly man-made toxin as his weapon of choice is terrorizing Boston and using the notorious Combat Zone as ground zero. As the Irish and Asian gangs that operate out of the area battle each other for territory, people are dying horribly. With the newly-elected Mayor of Boston at his wit's end, it all falls into the hands of a local infectious disease researcher, a less-than-honorable Boston Police Detective, and a private investigator combating demons of his own, to keep the city from exploding. And the clock is ticking.
