In August 1944, Royal Romania withdrew from the war. Then the pro-fascist regimes in Bulgaria and Yugoslavia capitulated. Soviet troops liberated the Balkans city by city, country by country. The war was ending, but more and more work appeared for the army counterintelligence. One day, the radio interception of one of the special units caught a strange transmission: “...Listen, listen! Rinne, Rinne. I'm Rale. The jacket is ready! The one-eyed one is swollen...” Searches on the air, as well as the advancement of our army, lead intelligence officers to unravel not only this transmission, but also a complex spy network of double agents.
