U-Boat 29

In this gripping 1939 spy thriller, Conrad Veidt stars as Captain Hardt, a German U-boat commander sent to the Orkney Islands in 1917 to gather intelligence on the British Grand Fleet. As he navigates a complex web of deception and double agents, Hardt finds himself torn between his mission and his growing attraction to his contact, Fräulein Tiel - who turns out to be a British double agent. With its tense atmosphere and unexpected twists, "The Spy in Black" (released as "U-Boat 29") is a classic black-and-white espionage drama that showcases Veidt's talent for playing complex, nuanced villains.
