Antonio Gutierrez, nicknamed Lonely, grew up in the United States and joined a gang before agreeing to leave the country rather than face serious criminal charges. In Michoacan, western Mexico, he joins the Autodefensas, a vigilante militia that has driven drug cartels and, in places, the police out of villages under its control. The film follows him as the cartels kidnap him once and the Mexican government moves to disarm and dismantle the Autodefensas, putting him and other members at risk from both sides. Interviews and on-the-ground footage from the villages he claims to protect sit alongside his own account of why he does this, whether from loyalty to the community that took him in or from something closer to personal revenge against the cartels who have already targeted him. The film stays with that ambiguity rather than resolving it, watching one man's choices play out inside a wider collapse of state authority in the region.
