Overview:The construction of the Vakhsh Canal, one of the largest new buildings of the first five-year plan, is underway. Two Americans are coming here under contract. A seasoned spy, Colonel Bailey, who introduced himself as the harmless traveler Mr. Murry, would later be caught red-handed and exposed. And Mr. Clark, who came to the "make money" channel, will gradually become convinced that work and politics are not such different concepts. Not accepting socialism, he quite sincerely sympathizes with the enthusiasm of the Soviet people. Love for the translator - Komsomol member Maria Polozova - helps Clark to comprehend what is happening.
