China's rise as the world's largest exporter of consumer goods rests partly on a system most of its trading partners never see: the Laogai, a network of more than a thousand prison labor camps where inmates manufacture goods for domestic and export markets. This film gathers former prisoners, many jailed without trial for political or religious dissent, who describe the factories where sleep was rationed and quotas were enforced through punishment. Charles Lee, held for three years over his practice of Falun Gong, recounts a year of attempted brainwashing that shifted, when it failed, into forced labor framed as "reform." Other survivors describe similar routines of intimidation and manual work inside camps that operate largely outside public scrutiny. Experts interviewed call the arrangement state-sponsored slavery and trace its contribution to China's manufacturing boom over the past two decades. The film does not chase spectacle; it lets the former inmates' accounts, plainly told, carry the weight of an economic system built partly on unfree labor.
