Once his past attendance at meetings of the Pasadena Communist Party in 1938 come to light, Qian gets caught up in the Red Scare of the 1950s. In this Part 2 episode, we see how the US government accused Qian of being a communist. Despite everything he had done for America and all the R&D that he might further contribute in the decades to come, Qian was deported back to his homeland. And from 1955 until his death in 2009, he went on to do all kinds of great things for the PRC's missile and space programs.
