Dictatorships throughout history have relied on fear and control to maintain power. The world has resoundingly condemned the atrocities of the Nazi concentration camps, the Soviet Gulag, and many other systems of repression around the globe, but has remained largely silent on one of the most extensive and repressive prison camp system in the world: the Chinese Laogai. Since the early 1950s, China has used the Laogai to crush dissent and root out potential sources of opposition, whether political, economic, or religious in nature, while simultaneously exploiting prisoners as a source of free labor.

Harry Wu was a political prisoner in China for nineteen years after being labeled as a counter-revolutionary by the government. Originally from Shanghai, he was part of the so-called bourgeoisie class and was a university student in Wuhan before he was unjustly imprisoned, without even a trial.
