After a mass shooting at a police funeral, ex-cop Gannon realizes that the killer belongs to the same militia he joined when he quit the force. Knowing they will be number one on the suspect list and the police will be closing in fast, Gannon calls his fellow militiamen to a remote lumber mill to lie low while working out a plan. Once there, he uses any means necessary to identify the killer and stop the violence before it escalates out of control.
