Ten crewed satellites in the United Nations’ Sigma Project are destroyed after colliding with a mysterious space barrier, a phenomenon that baffles scientists. A small missile-like capsule is recovered on Earth and handed to authorities, and when its contents are examined, a spoken message proclaims to be from the Masters of the Spiral Nebula Ghana—aliens who deem humanity a disease and announce a quarantine to protect the universe. The capsule’s origins remain elusive as analysts try to decipher its intent, setting the stage for a global tension that blends science, mystery, and fear.
On the way to a United Nations meeting, Richard Devon as Dr. Pol Van Ponder, the head of Sigma, is knocked off the road by a mysterious ball of light and dies. Unknown to the council, aliens have assumed his form to infiltrate Sigma, duplicating themselves into two copies of the scientist to extend their reach within the project. In the wake of these alien intrusions, a string of natural disasters erupts worldwide, fueling speculation that the warning from space is already beginning to unfold in the real world, unseen by most but felt by everyone.
Astronomer Dick Miller as Dave Boyer spots a troubling clue: Van Ponder bears identical markings on both arms, a sign of the duplicates at work. In the laboratory, John Compo, portrayed by Jered Barclay, joins forces with Dr. Howard Lazar, played by Eric Sinclair, and they race to understand the anomalous behavior surrounding Van Ponder. A dramatic moment comes when Van Ponder’s hand is scorched by a torch, yet the wound heals in front of their eyes, hinting at something far beyond ordinary physiology. John hurries to get Lazar’s help as the team grapples with the possibility that Van Ponder is not what he seems, and the tension within Sigma tightens as the countdown to launch begins.
Before the Sigma launch, the truth about Van Ponder begins to surface. He reveals his alien nature and, in a bid to secure an ally, attempts to recruit John; when John refuses, Van Ponder kills him. Sybil Carrington, Susan Cabot, arrives in the control room and confronts the alien impostor, while Lazar’s death is initially mistaken for a routine tragedy. David, bewildered by the mounting inconsistencies, presses Lazar for answers, and Lazar confirms John’s death as the result of the accelerated flight, though David remains unconvinced. Van Ponder even briefly simulates emotion by creating a heartbeat for himself, a moment that unsettles Sybil and reveals a whiff of humanity behind the alien guise.
The plot thickens as Van Ponder murders Lazar, and the investigation lands on David’s doorstep, leading to his arrest. Unaware of Lazar’s death, Sybil continues to search for him and encounters Van Ponder, who duplicates himself again in front of her. One replica pursues David while the other makes a dangerous, seductive advance toward Sybil. As the satellite nears the mighty barrier, Van Ponder orders the pilots toward it, pressing the crew to gamble with the fabric of reality itself. David confronts one clone and wounds it, and after a brutal struggle, he kills Van Ponder. The surviving replica with Sybil also dies, sealing the fate of the alien ruse.
With the threat neutralized, David initiates a radiation blast designed to propel the Sigma satellite through the barrier. He rescues Sybil from the radiation chamber just before the blast detonates, and the mission reaches its stark, cosmic conclusion: the Sigma satellite breaches Andromeda at the speed of light, a triumph tempered by the toll of violence and the melancholy knowledge that the universe remains vast, mysterious, and forever beyond complete human control.
