When Steve Nastos is wrongfully accused of murdering his dentist—a man whom he believes committed an unspeakable crime against his daughter—he decides to take the law into his own hands. Freed on bail, he attempts to track down the actual killer in a town where laws are seen more as guidelines and law enforcement agents adhere to their own moral relativism. Handicapped by a recovering alcoholic lawyer, a rogue cop, and a two-faced judge, Nastos has the cards stacked against him. As his estranged yet beloved wife inadvertently becomes involved in the case, the stakes become higher, and Nastos is forced to protect her.

After being recently cleared of murder charges, the disgraced and out-of-work police detective Steve Nastos reluctantly teams with his brash and similarly disgraced lawyer Kevin Carscadden for a paycheck. Nastos—who built his career on channeling the shadowy instincts within him to hunt dangerous predators—takes on a mission to track the whereabouts of Lindsay Bannerman, a troubled teen who is missing from her wealthy adoptive home. The trail Nastos and his lawyer pick up is one with a sadistic abuser on the other end and littered with lies, deceptions, and lifeless bodies. Torn between spiteful former colleagues—detectives who maintain Nastos belongs in prison for homicide—a wife who wants her husband to finally liberate himself from the darkness that fuels him, and the promise he made to a stranger to find Lindsay, the search is a race against time before everything vanishes forever into the dark matter.
