After the September 11 attacks, the Department of Homeland Security set up regional Fusion Centers meant to link federal, state, and local law enforcement into one intelligence-sharing network. This film traces how those centers grew far beyond that original mandate, pulling in private corporations as partners who trade data access for perks like protection against corporate espionage and advance warning on cyber-threats. Whistleblowers and researchers lay out how the public-private arrangement works in practice, who benefits, and what oversight looks like once a state agency and a corporation start sharing the same watch lists. The film also traces how the Covid-19 pandemic gave these centers a new emergency-management role, widening their reach into public health data. The result is a plain account of an infrastructure most Americans have never heard of, built for counterterrorism and now doing quite a lot more than that, with the people who worked inside it describing exactly how the lines between government and corporate interest blurred.
