The drama unfolds when detectives Tori Lustigman (Yael Stone) and Nick Manning (Noah Taylor) are assigned a brutal murder case. They begin to uncover mounting evidence to suggest the killing is connected to a spate of unexplained deaths, "suicides" and disappearances throughout the 80s and 90s. Is this the result of shoddy police work, indifference, or something far more sinister? Haunted by the disappearance of her teenage brother, Tori's fascination with the case soon turns to fixation. And when more ritualistic murders occur with the same bizarre signature, Tori and Nick will need to put their relationships, their careers and their lives on the line to finally reveal the truth.
