When construction workers discover human remains buried in a wooded area, Detective Marcus Holloway is assigned to a case in which the victim has been dead for years. There is no missing person report that matches the victim, and there is very little evidence left behind.
The first real lead takes Marcus and his partner, Detective Sofia Reyes, to an abandoned car that was towed years earlier and never claimed. But the deeper they dig into the victim's past, the more complicated the case becomes.
When someone connected to the investigation is brutally murdered and a key piece of evidence disappears, Marcus realizes this is no longer just an old case. Someone knows exactly what they are investigating. Someone is paying attention to every move they make.
