Historian Niall Ferguson travels through China asking one question: what does the state actually stand for? He interviews newly minted billionaires in the country's megacities alongside elderly survivors who lived through the chaos of Chairman Mao's Cultural Revolution, tracing a line from imperial dynasties through Communist Party rule to today's surveillance-heavy superpower. The film argues that Chinese governance has repeatedly demanded the individual submit to the collective, and it tests that argument against personal testimony rather than abstraction, letting people who suffered under Mao describe it in their own words. Ferguson also walks the gleaming infrastructure of contemporary cities to show what that unity has purchased. Location filming, archival material, and one-on-one interviews carry the argument, with Ferguson's own narration tying imperial history to Xi Jinping's China. The result is less a chronology than an inquiry into a single recurring bargain between state power and personal freedom, watched across two thousand years of Chinese history.
