Tank Man

Almost two decades ago, the horrible Tiananmen Massacre occurred. Thousands of demonstrators and students were mercilessly killed, most of whom were actually in the city of Beijing, not Tiananmen itself. After the massive crowd of demonstrators had been dispersed, one man rose in defiance against a column of tanks. His actions changed the world, but no one knows what became of him after his act of courage.

This documentary is about that man. (It's about 1 hour 15 minutes long.)
