A serial killer known as Red Smile is slaughtering his way through California, taunting the police with his riddles. Brian Warner and his partner Marcus James Reed are the two cops trying to take Red Smile down.
Brian Warner is an L.A.P.D. cop, 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?
