Query: Opportunity, oppression and an explosive opportunity

We are in the middle of the cold war. Too bad because we ar also victims of increasing population and decreasing farmland.Looks like Professor Soong Li (Keye Luke, of Charlie Chan fame) has invented an enzyme to produce extra cheap food. Unfortunately he is behind the iron curtain in Red China. The formula cannot come out so someone capable of understanding it must go in; Dr. John Hathaway (Gregory Peck) a scientist with scruples.Naturedly incase he can not get out they fitted his head with a micro-transmitter so he could relay the formula. They seem to have forgotten to tell him the transmitter was also a bomb large enough to take out anyone standing near.We see how ruthless and conniving the red's are and how they humiliate Soong Li for being a professor.Should we take revenge and a perfect opportunity as Dr. John Hathaway stands next to the Chairman (Conrad Yama?)
