When the British Empire dissolved after World War II, the City of London faced the loss of the offshore revenue that had sustained it. This film traces how bankers and lawyers rebuilt that revenue through a network of Crown Dependencies and Overseas Territories, from Jersey to the Cayman Islands to the British Virgin Islands, that now channels a large share of the world's offshore capital back through London. Interviews with insiders including Nicholas Shaxson, John Christensen, and former officials who helped design these structures describe how the City effectively became a tax haven for tax havens, retaining the deniability of a respectable financial center while its dependencies handled the secrecy work. Archival footage of imperial administration and postwar decline sets up the argument that formal empire never really ended, it just moved from flags and colonies into shell companies and trust law. The film lays out the mechanics of offshore finance in plain terms and argues this second empire has shaped the modern global economy as much as the first one did.
