The film opens with a concise interview sequence featuring a panel of consultants discussing the timeless question of what humanity would do if first contact with an extraterrestrial civilization inevitably occurred. This reflective prologue sets a calm, analytical tone before the action begins, highlighting the tension between curiosity and caution that threads through the entire story.
At the edge of the Solar System, a powerful and mysterious phenomenon known as the Orion Loop erupts with radiant energy, driving the crew aboard the Soviet spaceship Phaeton toward the unknown. To study this anomaly, a carefully assembled crew—matched with android doubles designed by a cyberneticist named Skryabin—is dispatched from Earth on a United Nations mission. The rationale behind creating these cyborg doubles is simple in theory: robots can endure extreme conditions and, by making them look like living team members, the crew can stay focused on their task without external distractions. The choice to rely on synthetic counterparts emphasizes the film’s exploration of what it means to preserve human life and judgment under extraordinary stress.
Upon arrival, the crew encounters something previously unimagined: holographic envoys representing a distant alien civilization that lived millennia ago on a tenth planet at the edge of the solar system. These emissaries carry a grave message about a galactic threat—the RZ virus, a disease that could devastate Earth—and they propose a bold plan to shield humanity. Their solution centers on sending a stream of relic neutrinos from their world, a project meant to create an energy barrier around Earth—the very barrier the investigators have been seeking to validate with the Orion Loop. The core conflict soon shifts from exploration to protection, as the aliens’ presence threatens to upend human assumptions about risk, intention, and contact.
Communicating with beings that exist in a form that directly interacts with human brains is perilous. The radiation from the holograms imposes mental strain, and the crew faces a stark consequence: two cybernetic doubles are lost in the process. In the ensuing effort to safeguard the ship, the navigator volunteers to venture into outer space to recalibrate the vessel’s protective measures; this mission exacts a heavy toll, inflicting extensive brain damage. The crew relies on groundbreaking medical technology—psychocontact—developed by the ship’s doctor, with the help of her mother, Anna Petrovna. Tragically, Anna Petrovna dies during the course of these experiments, underscoring the personal costs that often accompany scientific breakthroughs.
A pivotal figure among the crew, the cybernetician, interprets the aliens’ intentions as hostile. He seeks to destroy the very framework of the Orion Loop, but his actions have dire consequences: he injures the commander and attempts to reboot the ship’s computer to alter the mission. The attempt triggers a short circuit, resulting in his own death and damage to both the ship’s circuitry and the medical android, complicating an already delicate situation. The commander, undeterred, makes a bold choice to leave the spacecraft and travel through the loop’s center in an effort to demonstrate to humanity that the barrier is harmless. The gamble pays off in a surprising way: the commander’s wound heals completely, leaving no trace of injury, a moment that reframes the stakes for the mission and for any future contact.
Chaos and danger continue as a meteor shower strikes the engineer’s bay. A conflict arises when the engineer’s robot-twin tries to open an airtight door, risking a catastrophic depressurization. In a crucial moment, the real engineer deactivates the rogue twin just in time, preventing disaster. Although the crew fears the engineer has perished, the aliens intervene once more, saving him by enveloping him in an energy cocoon that defies the harshness of the vacuum and mechanical failure.
With the immediate threats contained, the envoys reveal a workable path for safe communication with the crew. Their message is clear and solemn: they come in peace. The ship, now buoyed by cautious optimism and a renewed sense of purpose, begins its return to Earth—an urgent preparation for what could be humanity’s first direct contact with an intelligent extraterrestrial civilization.
In the end, the story balances awe with responsibility, science with sentiment, and human resilience with the unsettling possibility that contact with the unknown may ultimately hinge on how we confront our own fears and ethics. The Orion Loop remains a symbol of both danger and hope, a boundary that the crew crosses not just with machinery and bravado, but with careful, compassionate restraint.
