In 1915 Berlin, the German high command grows anxious about Turkey’s alliance as British attacks on the Dardanelles hint at inside knowledge. Von Sturm, the head of German intelligence, suspects Ali Bey, the Turkish commander in the region, as the traitor responsible.
When his best agent has not been heard from in weeks, Kruger is given the assignment. Shortly afterward, Annemarie, known by the code name “Fräulein Doktor,” returns after completing her mission. She warns Von Sturm that Mata Hari has fallen in love with her target and can no longer be trusted. She also recommends sending an incriminating message using a code she believes Mata Hari has passed to the Allies. She further reveals that Kruger is not who he seems, uncovering that he is actually British double agent Bertram Church.
When Kruger is arrested at his dentist contact’s office, another patient, Douglas Beall, an American studying medicine in Germany, is taken into custody as well. Beall is later released. To be thorough, Von Sturm orders Annemarie to confirm Beall’s innocence.
Annemarie arranges a rescue from an unwanted “suitor” by Beall, who invites her to his hotel suite. During the evening, he confesses he has fallen in love with her, who is now going by the name Helena Bohlen. Helena is drawn to him, but when she reads a coded message from Von Sturm informing her that she has followed Mata Hari’s supposed guidance, she abruptly leaves.
Beall persists, however. When Helena boards the train to Constantinople, he follows on impulse and continues courting her, despite her half‑hearted attempts to discourage him. Her assistant Karl watches with growing concern. As they near the Turkish border, she orders Karl to return to Germany so Beall can use his visa.
To answer Beall’s persistent questions, Helena must admit she is a German spy. This revelation does not diminish his love. Meanwhile, she captivates Ali Bey with her beauty. When she accepts his invitation to dinner, she poses as British agent K-6 and negotiates for vital information. To gain his trust, she arranges for Beall to be framed as a spy by Von Sturm (who has arrived after becoming concerned by Karl’s reports) and supposedly executed by firing squad, though a French prisoner is to be substituted. His suspicions (and jealousy) are allayed, and Ali Bey is arrested by his Turkish superiors.
When Von Sturm finally confesses that he could not complete the switch and that Beall really was shot, Helena loses her sanity and is confined to a nunnery. Refusing to accept the truth, she remains convinced that her lover will find her and take her away. It turns out Von Sturm had lied in an attempt to avoid antagonizing a then-neutral America. In the finale, Helena is reunited with Beall.

In the summer of 1915, the great powers of Europe are locked in a desperate struggle that reaches far beyond the trenches of the Western Front. The Ottoman Empire’s position at the crossroads of continents makes the narrow Dardanelles a focal point of intrigue, and the shadows of espionage stretch from the grand salons of Berlin to the bustling bazaars of Constantinople. A climate of whispered rumors and diplomatic tightropes creates a world where a single misstep can turn a quiet afternoon into a matter of life and death.
In von Sturm commands Germany’s counter‑intelligence, a cold, methodical mind tasked with safeguarding his nation’s secrets. When he learns that the British may be tapping into crucial Turkish‑theater plans, the pressure mounts, and the stakes are made clear: the flow of information could tip the balance of a war still undecided. To verify his suspicions, he dispatches his most capable operative, a woman whose reputation for daring and intellect precedes her.
Annemarie, known in the underground as “Fräulein Doktor,” is a master of disguise and subterfuge, accustomed to moving unseen through hostile territories. Charged with a delicate mission to Constantinople, she must navigate a landscape where every encounter could be a trap. En route, she crosses paths with an unexpected ally, Douglas Beall, an American medical student whose curiosity and idealism draw him into the tangled web of intelligence work. Their meeting ignites a dance of wit and tension, each aware that the other’s presence could both complicate and illuminate the path ahead.
The film unfolds with a blend of tense period atmosphere and elegant suspense, punctuated by the oddity of a looming tea ceremony that threatens to become a pivotal moment. Against a backdrop of rival empires and covert agendas, the characters balance duty, desire, and the ever‑present question of whom—if anyone—can truly be trusted.
