Bernard Lee plays an irresponsible British warrant officer who loses his post in Warsaw. Lee is reassigned to a navy underwater weapons establishment in Portland. Humiliated, he falls for the entreaties of enemy spy William Sylvester, who recruits him to steal secret papers. Lee convinces a female coworker (Margaret Tyzack) that Sylvester is a NATO agent; thus, the woman is unwittingly sucked into the spy ring. The British turncoat outsmarts himself when he begins spending more money than he makes, arousing the suspicions of the government. Ring of Spies was based on the real-life Portland espionage scandal which dominated British headlines throughout the very early 1960s. ~ Hal Erickson, Rovi
