Natasha Mayston is shocked when someone knocks on her door late at night, not realizing it will be the last face she ever sees. Detective Dan Lockhart arrives at her home to investigate her death and is struck by its resemblance to a previous case. The cable-tie restraints and scratches on Natasha's wedding finger lead him to anticipate finding a metal ball in her throat—the same method used to kill another victim, Kim Hardy, months earlier in a different part of the city. Although Kim's murderer was caught, Dan suspects they may have arrested the wrong man. With a psychopathic serial killer potentially on the loose, he enlists the help of psychologist Dr. Lexi Green, who is determined to uncover the truth. As they delve deeper, another body is found, and Lexi discovers an online clue that could lead them to the killer. Despite skepticism from Dan's team, Lexi pursues the investigation independently, putting herself in grave danger. With time running out, can Dan connect the dots and apprehend the murderer before more lives are lost?
