What was once an unrelenting obsession in solving a crime has turned into something else — Frank breaking and entering, vicariously living through their lives, searching for a connection to anything.
One day he finds something waiting for him — a letter from a teenage girl who knows what he’s doing. It also says one other thing:
“Help, my father is raping me. Please kill him.”
Frank must decide how far he’ll go outside the law to save a child from a monster.
But his former ally, detective Mallory Black, is tracking his every move — she believes he escaped justice once, and she is not going to let it happen again.
Detective and ex-detective find themselves on a collision course as their lives are torn apart by their obsessions for delivering justice, no matter the costs.
