“Aeroporto – Restricted Area” follows the work of the Federal Revenue Service and other public agencies in monitoring and protecting Brazil’s airport borders. It highlights the tireless efforts of agents who safeguard the country from threats to public health, wildlife, flora, and the economy in the largest and busiest airports in Brazil. Tactical operations, risk assessments, and suspect inspections carried out through the cooperative work of multiple surveillance forces reveal an intense world–usually invisible to the thousands of travelers who pass through the airports every day: the restricted area.
