Brian Warner is an L.A.P.D. police detective, martial artist and the definition of no-nonsense cop. He is also a masked vigilante known as Black Shadow who hunts killers and does what the police can't: He works beyond the law to protect it. A serial killer is on the loose and a literal trail of blood brings Black Shadow to a murder scene of a young woman whose organs and other body parts have been removed, presumably to make identification harder. But what if there is more to this case than he thought?
