In a quick turn of events, they fall into the crosshairs of a corrupt sheriff and a violent underground government army. Sam and his brothers go on the defense, confronting these heinous legions head-on. As the battles of survival continue, Sam and his brothers are able to recruit some family friends along with retired military personnel. Sam and his small army soon become known as the Brothers3. The Brothers3 go on the offensive and battle across the United States. Death and violence are everywhere. The Brothers3 never know when they are going to be attacked.
