The Spider's Web: Britain's Second Empire explores the transformation of the British Empire from a colonial power into a modern financial powerhouse. The film examines how, as the empire began to disintegrate, British elites sought a new role in a changing world, ultimately finding it in the realm of global finance. Through the establishment of a complex network of offshore secrecy jurisdictions, the City of London successfully captured and funneled wealth from across the globe, effectively creating a second, hidden empire that continues to shape the modern world.
