A new case brings back old memories for Special Agent Kate Reid.
A cold case in Boston suddenly turns hot again when a construction worker uncovers bones at a site along Boston’s famed Charles River. The remains are presumed to belong to a victim of the serial killer who haunted the city in the 1980s. However, when more victims turn up and are believed to be much more recent deaths, the elite BAU team is called in to investigate the similarities.
The team, led by Agent Nick Scarborough, arrives to work with the local FBI field office. But this is all too familiar for Agent Kate Reid when parallels are drawn between this investigation and her own search for a killer who resurfaced years later.
Now she confronts not only the reminders of her former days, but someone is working against her interests that could undermine her very sanity.
