An Internet influencer and her boyfriend are brutally murdered on the Westside of Los Angeles, and Homicide Detective Casey Stafford is under pressure by the police department and the news media to catch the killer—but as he investigates, the murders continue. It appears that the suspect is covering his tracks by killing Casey’s witnesses, and each murder is crueler and more disturbing than the last.

The investigation leads Casey and his partner, Banchet, to a Chinese gang, a Mexican hitman, the FBI, a million dollars in stolen gold, and a leak in the LAPD itself, and with each murder, media interest in the case grows until the entire nation is watching.

Casey needs to stop the deranged murderer before he kills again, and he needs to do it before he is taken off the case by his commanding officers.
