In "Critical Incident: Death at the Border," a harrowing documentary-action hybrid, journalist John Carlos Frey delves into the 2010 tragic death of Anastasio Hernández-Rojas, an undocumented Mexican immigrant who succumbed to injuries while in custody at the border. A pivotal eye-witness video reignites a national conversation, leading Frey and a team of investigators on a perilous journey from the Arizona desert to the corridors of power in Washington D.C. As they dig deeper, they expose shocking cover-ups and uncover the existence of a clandestine unit within the Border Patrol linked to other border-related incidents, raising uncomfortable questions about justice, accountability, and the human cost of America's immigration policies.
