In Midcoast Maine, Jamie and her K-9 team search for the cognitively challenged son of a local animal hoarder, while recently licensed private investigator Jack Juarez looks into a murder related to the case. Unfortunately, each new clue Jack finds in the investigation seems to lead him back to a suspect police already have in their sights: Jamie's son. Meanwhile, Jamie fights to save a critically ill pit bull pulled from the hoarder's home who could hold the key to the woman's dark secrets.
