The Human Factor (1979)

In the shadowy corridors of the British Intelligence Africa division, MI6A, Colonel John Daintry embarks on a mission as the newly appointed security chief. Unbeknownst to the unsuspecting staff of the London office, it's more than just routine rounds. The office is rife with treachery, as crucial classified information has slipped into the hands of the Soviet Communists, a breach suspected to be an inside job. As Daintry probes the lives of the mid to low-level staff, his gaze falls on Arthur Davis, a mid-level bureaucrat with a penchant for port and female companionship. Davis' carefree, reckless lifestyle raises suspicions, making him a prime candidate for the leak. The real traitor, however, is Maurice Castle, Davis' friend and superior, who remains unnoticed due to his low-key life, the only anomaly being his forbidden love story with Sarah, a black woman he met during his tenure in South Africa. With the brass fearing that Davis might leak information to Moscow during his rendezvous with girlfriend Cynthia, they hatch a plan to quell the damage permanently. But the threat looms, and the information continues to slip through their fingers. As Daintry delves deeper, Castle's sense of impending doom heightens. Torn between his loyalty and the personal reason that pushed him into this double agent life, Castle faces a dilemma as the very thing dear to his heart comes under threat. In the world of espionage, where trust is a luxury and betrayal a common currency, 'The Human Factor' takes you on a suspenseful journey through a labyrinth of secrets, lies, and personal stakes.
