But when he is called to the scene of a school shooting, the professional and personal become intertwined, and he suspects that whoever is behind the crime may be connected to his own family tragedy.As Marsh and his partner Remy investigate the shooting, they discover that it is far from straightforward, and their search for answers leads them to a conspiracy at the highest levels of local government–including within the police force.
