Special Agent Sandy Banning and her team are at it once again... Nearly a year after almost being killed by a serial killer named Infinity Man, who's identity turned out to be one of the biggest betrayals that Sandy has ever experienced in her life, she is called back from her self-imposed hiatus; Master is back. One of the worst human traffickers that Sandy has ever had the misfortune of coming across, Master doesn't discriminate on who his victims are. Four years earlier, she and her late partner Ed had raided his compound and found a bloodbath with twelve dead women and Master no where to be found. Now a new body has been found in her jurisdiction with his trademark sign; the victim's ears have been notched. Even though Sandy is having difficulties believing in her investigative abilities after the number Infinity Man pulled on her, she doesn't hesitate to place herself right back in the path of a man who has vowed to bring vengeance down on her for being responsible for his loss four years previously. When two children become his next intended profit margin, Sandy knows that she can not let this man disappear again. She will need to do everything in her power to bring him down. As her team uncovers clue after clue as to Master's identity, it becomes apparent that there are strings being pulled by the man...and the puppet is someone close to her once again. On top of everything, she also has to deal with being pressured into becoming a donor for her mother who is dying of cancer. Sandy hasn't had anything to do with either of her parents in twenty years, ever since her fifteen year old baby sister's death. The bitterness over their addictions being the cause of her having to be the one to have to identify her sister's body still runs strong, even after all of this time. After a trip to Ohio looking for information on the woman they believe is his number one slave, Sandy and her boss and partner Special Agent in Charge Frank Gorring come away with a lead that could very well take them directly to Master's doorstep. When another victim is taken, this time someone close to Sandy, it becomes a race against time to rescue all three victims before they disappear for good into the dark underworld of the human black market? Can Sandy put aside her nightmares and her insecurities long enough to bring down Master before he brings her down? Join Sandy and her team as they begin another harrowing investigation into the mind of a psychopath.
