Dr. Sorge is a spy whose cover is that of being a journalist. Sorge is in Japan, and built up the ‘cricket' espionage network. Sorge's good connections to the German embassy in Tokyo permit him to report to Moscow on important decisions, such as the Japanese attack on Pearl Harbour, well before they happen. When two of his associates are arrested, he tries in vain to flee. A secretary at the German embassy, who has loved Sorge without knowing what he was up to, smuggles a poison pill to him in prison, so that he can be spared a death by hanging. For her efforts she is arrested as an accomplice.
