Film 'Sonic Deception' shows the use of sounds to deceive the enemy (sometimes described as the "Ghost Army" in World War 2). Dramatization shows United States troops crossing river in small boats and arriving on beach. They establish beachhead on river bank and defeat German troops located there, having arrived by suprise. Film recounts through actors how a German spy at a German army corps headquarters informs about the presence of United States tanks and trucks. Film demonstrates how sound recordings were used by U.S. soldiers to create false impression of troop activities including bridge building and tank and vehicle movements, in order to serve as a decoy and mislead Germany enemy forces about U.S. Army activities. Dramatization shows German officials consulting and looking at maps. German soldier looks through binoculars and informs officials through phone. Tanks cross a bridge and artillery on field. Actual scenes of front gate of Army Experimental Center station headquarters at Pine Camp in Great Bend, New York (upper New York State). U.S. Army soldiers are shown recording via microphone the sounds of actual bridge construction at the center. The microphone routes to a recording truck where a turntable for pressing recordings is running, creating a phonograph recording of the bridge building decoy sounds. Recording of other sounds is shown, including sound of a bulldozer at work, sounds of men unloading trucks, and sounds of tanks crossing a bridge. Soldier is seen selecting a phonograph record from the Army Experimental Station Library.

Liberated United States prisoners (mostly military airmen) at POW camp called Kriegsgefangenen-Mannschafts-Stammlager (Stalag) VII A, located just North of Moosburg, Germany. The airmen cook food. Several are seen sunning themselves. Airmen seen shaving, shining shoes and cleaning clothes. A group of airmen around sign 'I Wanted Wings' and 'Luft 3'. These are some of the prisoners who were originally held at Stalag Luft III, in German Province of Lower Silesia, near the town of Sagan (now in Poland).
(Note: Stalag Luft III is famous because the "Great Escape" took place there in March, 1944. Prisoners were forced to march from Sagan to Spremburg during the coldest winter in Germany in 50 years. There, they boarded a train of boxcars for a 3 day trip to Moosburg in January 1945, because the Russians were closing in. The addition of these prisoners to Stalag 7A, at Moosburg, led to serious overcrowding of the camp. On May 1, 1945, the New York Times reported that "The Fourteenth Armored Division liberated 110,000 Allied prisoners of war at Stalag 7A at Moosburg." This corrected an earlier report that 27,000 prisoners had been liberated.)
