pilot Jim Brennan, Errol Flynn returns to Istanbul for the first time in five years, and his arrival is quickly shadowed by a suspicious encounter with Insp. R. P. Nural, John Bentley, who suspects him of diamond smuggling. He heads to his old hotel, only to find that his familiar room is now occupied by Charlie Boyle, Leif Erickson, and Marge Boyle, Peggy Knudsen. In the bustling cafe, Jim sits at his regular table and reconnects with memory, recalling a time when he shared a drink with a captivating German tourist, Stephanie Bauer, Cornell Borchers, a woman who understands the life he leads and nudges him toward a dangerous, quick job flying businessmen to Cairo. Stephanie’s charm and confidence draw him in, and she becomes the spark that pulls him deeper into a web of danger.
At a crucial moment, Aziz Rakim, Vladimir Sokoloff, a shrewd merchant, offers Jim a bracelet to be delivered to Stephanie. What seems like a simple gesture hides a concealed compartment filled with diamonds, a plot that Jim cannot dodge. He stashes the glittering loot in the ceiling fan, a secret he guards as tightly as his own flight plan. When Jim proposes to Stephanie, he also discreetly hands her the bracelet, and she accepts, though danger soon closes in. Paul Renkov, Werner Klemperer, and his henchmen appear, beating Jim and forcing the issue. The pair are pressed by Mr. Darius, Martin Benson, the crafty leader who demands the diamonds, setting the stage for a dangerous game of pursuit that draws the police into the drama as Insp. Nural closes in.
The police uncover that Aziz Rakim was murdered, likely tied to the diamonds smuggled inside the bracelet. Jim, adamant that he has no involvement, vows to leave for Paris with Stephanie. But trouble multiplies when Stephanie’s hotel room is invaded and the bracelet is stolen by Darius’ men. Jim escapes a direct confrontation with Nural only to discover that the diamonds remain in play. He and Nural attempt to stage a move, impounding his plane and coordinating a hold until Jim exits the country, but a blaze erupts at Stephanie’s hotel, trapping the lovers in the flames. Jim fights his way through the inferno to save her, but the burning building forces him to retreat, and Stephanie’s fate hangs in the balance.
Years pass, and Renkov surfaces again with a new demand: Darius wants the diamonds back. Jim learns that the couple who once occupied his old hotel room—now married and living under the name Douglas Fielding, Torin Thatcher—are in danger, and he returns to the scene. To his astonishment, Stephanie is still alive, though altered by time and memory; she does not recognize Jim, having become Karen Fielding in order to shelter herself from the past. Douglas, a man who once saved Stephanie during the original hotel fire, is still by her side, and the memories of what they shared begin to flicker in her mind.
Jim presses for answers about Stephanie’s past, but Douglas asks him to leave her be. The bracelet remains a tether to what once was, and Stephanie privately slips away to visit Jim at the café, clutching the bracelet and trying to recall the feelings that once awoke in Istanbul. Jim’s attempt to reclaim the diamonds leads to a close call with Nural, and he discreetly slips the diamonds into one of the Boyle’s suitcases, hoping to hide them from the tightening noose.
With pressure mounting, Jim allows himself to be captured by Renkov and is taken to an abandoned warehouse where Darius has kidnapped Stephanie. There, Jim convincingly asserts that Stephanie is the true thief, prompting Darius to set the warehouse ablaze in a desperate bid to erase the past. In the ensuing chaos, Jim retrieves Stephanie and returns her to her husband, ending the immediate danger—yet the dawn brings a fragile equilibrium. The next morning, as Jim prepares to fly out of Istanbul, Stephanie wakes and calls his name. The airplane crew and Inspector Nural watch in cautious hope as Jim appears to fly under the cloud of diamonds, and yet the moment of true departure is stalled when Stephanie’s reaction reveals a hidden connection. The inspector’s guidance hints that some force, perhaps love or fate, will compel Jim to return to Istanbul, where a reunion waits with the promise of resolution and the chance to face the past together.
