Spy for Germany

The Nazi agent Erich Gimpels is put ashore, in 1944, on the coast of the USA by a submarine of the German Navy. He is to scout out the possible use in the war of an atomic bomb against Germany. From his New York hotel room he picks up conspirative contacts. The FBI is soon on his trail. Gimpel discovers that the bomb is almost ready. He is just about to break off his mission and emigrate to South America with his girlfriend when he is arrested and sentenced to life imprisonment. He was pardoned in 1955 by the USA.
