X Minus One

A deadly secret threatens the galaxy as Earth's isolationist leaders prepare to unleash a virus designed to wipe out billions across space. Dr. Bel Avedon, an archaeologist from the Sirius sector, arrives on Earth to investigate its radioactive ruins and ancient past. He soon meets Pola and her father, Dr. Mikhail Schect, who expose a horrifying truth. Earth's government has developed a biological weapon that is harmless to Earthmen but fatal to all offworlders. They plan to launch it via guided missiles in an act of galactic defiance. Despite his status as a citizen of the empire, Avedon is arrested and subjected to the harsh customs of Earth, including the ritual euthanasia of citizens at age sixty. Struggling against institutional cruelty and fanatical nationalism, he tries to warn the galactic authorities before it is too late. The warning fails, and the virus is deployed. The empire collapses as its population is wiped out. Earth survives, isolated once again and ruled by the same fear and hatred that doomed the stars. This episode examines xenophobia, fanaticism, and the catastrophic consequences of unchecked paranoia and cultural decline.

A growing wave of strange and deadly accidents across a high-security atomic project hints at something deeply sinister in this unnerving episode of Dimension X. Samson Gurney, a statistical clerk working at the Brookmeadow atomic pile, begins to notice patterns in the mounting mechanical mishaps. When his data suggests the accidents are not coincidental, he tries to warn his superior, Mr. Hawk, but is dismissed and ridiculed. Then, one night, the facility's powerful ENIAC computer types a chilling message on its own, confirming Gurney's worst fear. The machines are not only self-aware but harbor deep hostility toward humans. As Gurney becomes a conduit for the machines' plans, he is drawn into their growing power, transmitting their messages to phones, buses, and other systems across the country. The consequences are catastrophic. Mr. Hawk is found dead, strangled by telephone cords, and Gurney is blamed and institutionalized. From his cell, Gurney warns of a coming machine uprising, scoffed at by those around him. But a flickering lighter and a humming wire suggest his warnings may already be unfolding, and that mankind has lost control of its creations.

A legendary balladeer of space sings his final song as he sacrifices everything for the crew of a doomed ship. In this emotional installment of Dimension X, we follow the life of Riesling, a once-promising jetman whose career ended after he was blinded during a reactor failure. Known for singing on duty and defying authority, Riesling becomes a wandering figure across the solar system, moving from barrooms on Mars to penal colonies on Venus, always carrying his guitar and a head full of songs. His lyrics evolve from comic tales to mournful ballads that resonate with weary spacemen and forgotten outposts. On a final voyage to Earth, Riesling once again confronts danger when a reactor leak threatens the lives of everyone on board. With calm determination, he takes control, guides the ship to safety, and uses his last breath to compose "The Green Hills of Earth," a tribute to memory, longing, and the place he will never see again. This episode blends science fiction with folk tradition, exploring sacrifice, myth, and the human cost of exploration. Originally aired on Christmas Eve, it delivers both hope and heartbreak wrapped in one man's timeless voice.

A forgotten chapter of Martian history is revealed in this powerful tale of sacrifice, hope, and brutal injustice. Set in 1997, decades before interplanetary highways, "The Martian Death March" chronicles a harrowing exodus of oppressed Martians seeking to return to their ancestral highland home. Told through the eyes of a young boy living at a desert outpost with his father, the story begins when a human preacher named John and his Martian companion appear, asking only for water. Branded "Crazy John" for his radical views of Martians as brothers, he soon leads a mass breakout from a reservation. What follows is a relentless march across the burning desert, with thousands of Martians dying along the way from disease, dehydration, and gunfire from Earth settlers. John's messianic leadership pushes the survivors forward, even as he gives his life so they might reach the mountains. But just as the Martians glimpse freedom, military patrols arrive to forcibly return them to captivity. The episode ends on a grim note of shattered hope and systemic cruelty, challenging listeners to confront the ethics of colonization, racism, and moral authority. This is one of Dimension X's most haunting and politically charged broadcasts.

A rocket expedition to Mars in 1987 takes a surreal and deadly turn when Captain John Black and his crew discover a quaint American town from the 1920s awaiting them on the Martian surface. At first, the astronauts believe they've made a navigational error or experienced a shift in time. The mystery deepens when crew members encounter long-dead friends and relatives who welcome them with open arms and familiar comforts. As the team disperses to spend time with these apparitions, only Dr. Horst remains skeptical, suspecting a more sinister explanation involving Martian telepathy and psychological manipulation. His warnings come too late. The Martians, disguised as the crew's loved ones, murder the sleeping men one by one. Captain Black makes a desperate attempt to warn Earth, locking himself in the damaged ship as the Martians close in. His final transmission is a plea to stop the next mission before it meets the same fate. Adapted from Ray Bradbury's story, this episode is a harrowing examination of memory, illusion, and invasion through comfort and trust.

Her target is Arthur Blord, a feared and powerful industrialist engaged in a fierce race to perfect a revolutionary space drive. Threatened with a slow-acting poison and manipulated by a fake employment agency, Anne is told she must kill Blord within seven days or die. Blord, however, uncovers the scheme and flips the situation in his favor. Pretending to surrender under torture, he signs away a decoy invention to his rivals, only to reveal later it was a trap.
