Brian Warner is a 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 loose and while investigating, Black Shadow figured out that it is a cannibal case. He met the boyfriend of the latest victim, a hacker who mistrusts the police but may hold the key to solve this case. And so Black Shadow and Marcus Reed bring him in for questioning.
