Conrad Parker has been hired by the CEO of Star Enterprise, a pharmaceutical tech giant. As an unstable ex-military man with questionable moral lines himself, he is equipped with the set of skills necessary to clean up questionable and sometimes unethical activities.

Conrad finds himself deep within the Star testing laboratories investigating Star's increasingly disturbing fiscal decisions. After being bitten at the laboratories by a genetically engineered rat, the size of a small dog with an insatiable thirst for human blood, Conrad's blood type has mutated from Rh Positive to Rh Negative. This turn of events has consequences that no one could possibly expect.

Frustrated by these unforeseen events and searching for answers to the origins of the manipulated rats and a cure, Conrad embarks on an intense uncharacteristic journey that will unravel just how deep the corruption runs.
