In the spring of 1939, England-born scholars cross the Atlantic of danger and adventure as Richard Myles, an Oxford-educated professor, and his new bride Frances Myles embark on a honeymoon that quickly turns into a high-stakes mission. Tasked by the British secret service to locate a scientist who has devised a countermeasure against a new Nazi secret weapon—the magnetic sea mine—the couple treats the assignment as a thrilling puzzle across war-darkened Europe. What begins as a romantic journey soon becomes a covert chase fraught with risks, coded signals, and clandestine contacts that test their wits and their bond.
Their first signal comes in Paris, where Frances is given a hat adorned with a rose as a discreet sign for their enigmatic contact. A silent instruction sends them toward a Montmartre café, and an unseen intermediary hides a clue in a tour guidebook slipped into Richard’s coat. On the page, ink dots sketch a musical staff that bears the opening notes to the haunting line, “My Love Is Like a Red, Red Rose.” The password is cryptic yet beautiful, a key that unlocks a shadowy sequence of revelations as they chase one lead after another across a continent on the brink of catastrophe. Three pinpricks along the map guide them to a book dealer in Salzburg, where Mr. A. Werner provides a vital breadcrumb and points them toward a museum where a man who calls himself a “guide” presides over their next steps. This figure is Hassert Seidel, a chilling presence whose manipulation of information cues a perilous detour toward a guesthouse run by Frau Kleist.
The trail grows thicker with every stop. An annotated volume on Franz Liszt points them toward Pertisau in Tyrol, where a doctor who collects chess pieces becomes a piece on the board they must understand to outmaneuver their enemies. The couple attends a Liszt recital, hoping the music will be a cue to safety, but a moment of tension erupts when a Nazi commandant is shot during a passage Thornley had practiced earlier. The ensuing chaos pulls Richard and Frances into a crisis of trust, and they are eventually rescued by the Gestapo’s sharp-eyed commander, Sig von Aschenhausen, a former Oxford classmate of Richard’s who now looms as both ally and obstacle. The rescue is tempered by the brutal reality that Thornley, fighting back against oppression and violence, has his own reasons for clinging to vengeance.
The search leads them to the home of Dr. Mespelbrunn, a renowned chess piece collector who hides the crucial secret they seek. The atmosphere is taut with danger as von Aschenhausen’s presence suggests a dangerous intertwining of loyalties. The doctor’s house becomes a silent theatre of suspense, with a piano holding sheet music that echoes a deeper cipher, and a warning from Mespelbrunn that they are being hunted by the Gestapo. Richard and Frances realize they must act quickly: they rescue Mespelbrunn, who reveals his true identity as the missing scientist with the critical countermeasure, and they join forces with Count Seidel to escape the tightening net. The revelation that Mespelbrunn is the scientist behind the crucial invention reframes their mission from pursuit to protection, and the quartet sets a plan into motion to reach safety in Innsbruck.
Armed with counterfeit passports supplied by the elderly Schultzes, the couple and their new ally navigate a perilous journey toward Italy. The plan, however, hinges on precise timing and the fragile trust of those who inhabit this shadowy realm. A dangerous detour at a border crossing forces a tense separation and abrupt, heart-pounding decisions. Frances is detained and questioned as the Gestapo closes in, while Thornley races against the clock to join Richard in pursuit of the same escape route. The trio—Richard, Thornley, and Seidel—breach the interior of Frances’s captivity, taking on the guards and seizing the moment when the border guards are distracted by their ruses. The fight culminates in a violent confrontation that costs Thornley his life but secures a fragile, hard-won escape.
Finally, with cunning, courage, and a carefully mapped plan, the survivors fool the Nazi guards and slip into freedom, crossing into Italy as the march of oppression recedes behind them. The mission has succeeded in acquiring the countermeasure against the deadly weapon, but at a heavy price. The journey across Europe—its cities crowded with secrets, its landscapes echoing the tension between science and tyranny—has forged a shared destiny for Richard Myles and Frances Myles, two newlyweds whose bond has been tempered in the fires of espionage and courage.
> "My Love Is Like a Red, Red Rose." This phrase, woven through their clues, remains a thread of memory as they press onward, a reminder that love can endure even when nations tremble.
In the end, the story moves from a personal union into a larger struggle for scientific security and political survival, with the couple’s perseverance and the allies they trust proving essential to outwitting a regime bent on domination. Across Innsbruck, border crossings, and the shadowed corners of Europe, the mission unfolds with meticulous detail and a restrained, realistic tone that honors the peril of the era while celebrating the resilience of those who choose to resist. The film’s blend of suspense, wit, and human connection remains an enduring portrait of courage under pressure, anchored by its central pair and their unlikely circle of allies.
