There's a killer inside all of us...
After an elite criminal profiling unit is shut down amidst a storm of scandal and mismanagement, only one person emerges unscathed.
Forensic psychologist Doctor Alexander Gregory has a reputation for being able to step inside the darkest minds to uncover whatever secrets lie hidden there and, soon enough, he finds himself drawn into the murky world of murder investigation.
In the beautiful hills of County Mayo, Ireland, a killer is on the loose. Panic has a stranglehold on its rural community and the Garda are running out of time.
Gregory has sworn to follow a quiet life but, when the call comes, can he refuse to help their desperate search for justice?
