Set in Stockholm, Sweden, in the present year, this gripping tale follows a determined scientist as he guards a breakthrough that could shift the balance of power. Dr Nils Ahlen [John McCallum] of the Institute of Technical Research is set to travel to Uppsala University to present his astonishing energy-storage device. In the calm, ordinary moments before departure, he reviews logistics with his loyal assistant Sven Nystrom [Anthony Dawson], even showing him the hidden key to the laboratory “just in case.” The domestic scene touches on a quiet tension as his wife, Helga Ahlen [Mary Laura Wood], complains that they’ll miss a dinner with friends, and he gently suggests she could go without him. The ordinary rhythms of life frame a discovery that could change everything.
At Uppsala University, Ahlen’s demonstration ignites intense interest, especially from a colonel in the Swedish Army. The device stores vast amounts of energy as audio on barium discs, and when played back, these discs release enough power to fuel a town or to propel a rocket or flying bomb across the Atlantic. The sheer potential draws military curiosity and urgency, and the demand for specifications arrives with remarkable speed—almost “by yesterday.” The spark of scientific triumph tethers itself to a race for what comes next, and the stakes are no longer theoretical.
When Ahlen returns home, his apartment has been disturbed. The key to the laboratory is gone, and the crucial components of the recorder are missing. Alarm bells sound as he alerts the police and the head of his institute, but the investigation quickly reveals that his trusted assistant Nystrom is missing as well. Frustrated with the pace and methods of the official inquiry, Ahlen resolves to take matters into his own hands and begins to pursue the trail himself. The pursuit leads him to a rendezvous in Karlstad with the enigmatic Baroness Erland [Naima Wifstrand], a figure who seems to know more than she will admit. Erland denies any knowledge of Nystrom, though she matches the description of a frequent visitor from Nystrom’s records. As Ahlen is leaving her residence, Erland’s manservant mentions a call from Leksand, hinting at the broader reach of the pursuit.
Peterson, the police inspector [Jack Warner], traces the thread to Erland and soon crosses paths with Ahlen. The two decide to join forces, pooling clues as they uncover that a plane was forced to land at Leksand, and that Nystrom and Helga were aboard. The two couples—Ahlen with Peterson, and Nystrom with Helga—are thrust north toward the border with Finland, a path that suggests a bid to move the invention beyond Sweden, perhaps into the hands of another superpower. The narrative then switches between the two pairs, tightening the suspense as the landscape grows more forbidding: blizzards, lonely roads, and the fragile edge between scientific genius and geopolitical leverage.
Their chase takes them into the rugged domain of the Sami people, often referred to as Lapps. Nystrom and Helga hire three Sami guides, while Ahlen and Peterson join a large family group guiding their reindeer across the border. The presence of outsiders immediately stirs tension among the Sami, who view outsiders as bad luck or a distraction from the fragile balance of life in the mountains. Yet the village’s leader, Anders [Peter Blitz], supports the outsiders and persuades the others to tolerate—or even assist—their passage. The camaraderie of necessity and the weight of cultural clash color every encounter as the fugitives press on.
Tensions rise when Nystrom and Helga lay a false trail, steering Ahlen’s party toward disaster. A cliff edge and a destroyed reindeer herd become a harsh consequence of misdirection, and Anders, wracked with remorse, takes his own life, fracturing the group. The remaining travelers—Ahlen and the young Sami hunter Kara Niemann [Nadia Gray]—form a fragile alliance, and a new emotional thread develops between Ahlen and Kara as they navigate a landscape littered with peril and moral ambiguity. Kara’s loyalty to her people becomes a counterpoint to Ahlen’s scientific urgency, and a tentative bond begins to bloom amid the snow and ice.
The search for safety becomes a fight for survival as Kara’s group encounters wolves. Lacking heavy firepower, they rely on cunning and the skill of eagle hunters who command birds to protect the camp. An extraordinary sequence unfolds as multiple birds descend to strike fear into the wolf packs, a spectacular blend of myth and pragmatism that signals the hidden valley’s ingenuity and resilience. The four protagonists are drawn into the eagle hunters’ village, a sanctuary tucked away in a valley that feels almost Shangri-La, yet always haunted by avalanches looming above the narrow passes.
Within the valley, Helga is placed under arrest along with Nystrom by Peterson, and the couple’s painful confession unfolds. Helga reveals that loneliness and frustration spurred her actions, challenging Ahlen’s obsession with glass tubes and wires more than with flesh and blood. The moment carries a weighty ache as Ahlen pleads with Peterson to show mercy, pleading for a chance to let the pair go free. Peterson remains stern but there is a palpable sense that he might turn a blind eye—a nuanced note about duty, doubt, and human mercy. The tension tightens around the fate of the group, and a plan begins to form in the tense quiet of a snowbound refuge.
Then, in a desperate bid to escape, Nystrom and Helga decide to cross the mountains above the village. The locals join the chase, driven by fear of avalanches that could devastate their fragile sanctuary. The pursuit becomes a dramatic clash of motivations as Ahlen and Niemann urge restraint while Nystrom holds the line with a dangerous resolve. A violent confrontation erupts when Nystrom fires upon the pursuing party, triggering an avalanche that tears down the mountains and seals the fate of the fugitives. The blast of snow wipes out the escapees but spares the valley itself, leaving the Sami to reckon with generations of fear and the cost of fear itself.
As the snow settles, the community reflects on the long arc of fear they have endured, and the story closes with a sense of renewal. Ahlen and Niemann, now free to pursue their unlikely bond, look toward a future that is both hopeful and precarious, knowing that the invention’s power remains a powerful, dangerous possibility in a world full of competing ambitions. The ending lingers on the idea that courage, love, and a willingness to share knowledge can outpace paranoia and tyranny, even when danger still lingers at every bend in the road. The weather may be unforgiving, but the human spirit endures.
the weather is visited on the just and unjust alike
