Homicide detective, Bob DiStanza, has been doggedly pursuing an active serial killer operating throughout the city of Philadelphia. As the lead investigator of a dedicated taskforce commissioned to stop this highly disciplined yet unyielding predator of women, Bob struggles with the situation's grim reality. The investigation is going nowhere.

That's about to change. Abrupt alterations in the crime's behavior begin to further baffle the long stagnant detective. There are sudden changes, changes that make little sense considering the strict adherence to repetition the killer has shown throughout his reign of terror.

Bob, however, isn't the only one who's become aware of these variations in activity. The killer has taken notice as well, and he isn't happy about it.

Sometimes an entity can work between good and evil, exist only amid the gray shadows that connect black to white. Steadfast in its purpose, neither cop nor criminal can stand in its way.
