Why would US military veterans take up arms against the country they swore an oath to protect? Through gripping personal perspectives from all sides of this ongoing crisis, Against All Enemies goes deep inside the violent extremist movement in America, alongside the Proud Boys, 3 Percenters, and with never-before-seen footage of the Oath Keepers. These groups, organized and led by highly trained military veterans, pose one of the greatest threats to the United States today. While most veterans are successful in their transition to civilian life, an increasingly radicalized element is drawn to the insurrectionist movement. We saw evidence of this during the January 6 Capitol riots, but the danger goes far beyond a single day. The film explores the historical roots of the insurrectionist cause, its powerful draw for today's veterans, and the top-cover being provided by highly decorated former military officers and political leaders. Against All Enemies is both a warning about an existential threat to our democracy, and a beacon for those hoping to combat it.
