Inspired by true events, SOVEREIGN is a tense and provocative true crime thriller about a father and his teenage son ? Jerry and Joseph Kane (Nick Offerman and Jacob Tremblay) ? who follow the Sovereign Citizen belief system, a deeply anti-establishment worldview rooted in distrust of government authority. As the pair travel across the country delivering self-taught legal seminars and pushing back against systems they believe have failed them, their journey brings them into conflict with Police Chief Jim Bouchart (Dennis Quaid), setting off a tragic chain of events that forces a reckoning with power, principle, and the limits of freedom.
