Jim Richards returned home to Philadelphia after serving two years in the Military Police. He expected a joyful reunion with his fiancé, but learned she died after being brutally raped and strangled. Richards discovers she was the victim of a serial killer, possessed by a bloodthirsty demon, and he vows to hunt him down and kill him. Although the police claim they still are unable to identify the killer after a two-year investigation, Richards and a few former MPs go after him, armed with knowledge unavailable to the police. His team must also deal with drug dealers, gunrunners, and an old adversary from his days in the Army. Richards also discovers the spirit of his deceased lover has not yet left this earth and shares the spirit of an infant.
