Ring of Spies 1964

Harry Houghton, Bernard Lee, is a dissatisfied and alcoholic embassy attaché who embarrasses himself at an official garden party in Warsaw. Knowing he is to be disciplined the next day, he says goodbye to his girlfriend, who reports back to the Russian embassy about his likely return to England. Despite a poor report from his previous superiors, Houghton is posted to the top secret Admiralty Underwater Weapons Establishment at Portland, a highly secure Royal Navy facility where new weapons and equipment are tested under tight surveillance.

Houghton is soon approached by secret Soviet intelligence, who ask him to hand over documents they claim he already supplied in Warsaw, using the threat of blunt blackmail to press him into cooperation. He agrees to play along, but only for money. Soon after, he begins an affair with a fellow records clerk, Ethel “Bunty” Gee, who has access to more sensitive documents and is groomed by Houghton and his enigmatic handler, Alex. Together, the pair start to siphon off top secret files for Soviet intelligence, trading them for cash and the lure of a easier life abroad. The danger grows as the base’s routine hums along, and the stakes rise with every document they pass along.

When a fellow officer at the Portland establishment receives poison-pen letters, suspicion falls on Houghton among others, and the security apparatus tightens its watch. As part of routine counter-espionage, the authorities plant listening devices in Houghton’s home and soon hear Alex named as a key money source, tying the string of betrayal back to the couple and their accomplices. The net closes in as the story widens to include Peter Kroger [David Kossoff] and Helen Kroger [Nancy Nevinson], who also transcribed and transmitted information to Russia, and are arrested and brought to judgment at the Old Bailey.

The film opens with a pre-title prologue that traces the long history of spying, casting its themes in a historical light, and it closes with an epilogue that delivers a stark warning to cinema-goers: spies could be present in the audience, perhaps even in the very row from which they watch the movie. Throughout, the tension comes from a world where loyalty, money, and danger intersect in quiet offices, smoky rooms, and secure bases, reminding viewers that espionage is a quiet, pervasive force that can alter lives with a single act of betrayal.
