Maj. Gordon Towers William Leslie and Capt. Webber Carl Crow return to Space Station X-7 after gathering geological samples and ice from newly discovered Moon ice caves. The homeward leg is tense but uneventful until Webber suddenly collapses, and the crew rushingly carries him to the infirmary, where Dr. Hoffman begins a careful, puzzling examination. The station hums with activity as Towers is joyfully reunited with his girlfriend, the civilian biochemist Faith Montaine Dolores Faith, whose expertise will soon be crucial to understanding a mystery that could threaten everyone on board.
Dr. Faith Montaine notes a troubling clue—a small welt on Webber’s leg that quickly grows into a spreading fungus. Her instinct points to the Moon’s ice caves as the possible source of the spores, prompting the team to place Webber in isolation while they investigate the bizarre infection. The atmosphere aboard X-7 grows increasingly claustrophobic as the fungus advances, and Hoffman’s diagnostic caution hints at a danger far beyond a simple space illness.
Meanwhile, the station’s commander, Col. Frank Cromwell Richard Garland, begins to behave with unsettling oddity. As a swarm of meteors closes in, his hesitation to issue evasive maneuvers becomes apparent, and he is only nudged toward action by the ship’s communications officer, Lt. Connie Engstrom Pamela Curran. The mounting tension within X-7 mirrors the external threat from space, while the fungus tightens its grip on the crew.
Tragedy strikes when Webber dies, his body horribly disfigured by the fungal growth. Cromwell studies the corpse with eerie calm and mutters, “There’s nothing unusual in there,” refusing to report the death to Gen. Knowland on Earth Control Center. He warns Towers, Faith, and Hoffman to keep silent about the fungus lest panic rip through the station. Hoffman’s cautious inference is blunt: Cromwell is on the verge of space raptures, a serious illness masquerading as steadfast leadership.
To counter what he sees as mutiny, Towers attempts to remove Cromwell from command, but Cromwell calls it mutiny in return. The confrontation escalates as Connie covertly records the mutinous orders and transmits them to Earth. Knowland detects the anomaly—space weapons had been outlawed since 1970, long before X-7’s mission—and recognizes that a broader threat could be at stake. If the fungus spreads to Earth, drastic, even devastating, decisions may be required to prevent catastrophe.
As the infection worsens, Hoffman’s condition worsens too, and he becomes gravely ill. Yet he manages to convey a crucial fact to Faith and Towers: the fungus can be killed by cold. With this new knowledge, the team makes a renewed, perilous effort to regain control of X-7. Cromwell, now fully gripped by space raptures, sabotages communications and escapes confinement to threaten the ship once more, a desperate act that is quickly followed by recapture.
The turning point comes with a daring plan: to lower the interior temperature of X-7 below freezing. Freezing the fungus inside would effectively halt its growth. The unexpected twist, however, is that the fungus then begins to spread on the outside of the station. A staff officer explains that the heat from the unshielded Sun is driving the exterior growth, a clue that reframes the crisis. Gen. Knowland devises a bold counterstrike: launch a rocket to create a cloud of ice crystals—an icy corridor for X-7 to pass through, silencing the growing fungal threat.
The risky maneuver succeeds. As the interior chill takes hold, the fungus on the exterior is killed, and the station stabilizes. With the critical systems repaired, Towers reestablishes contact with Earth and requests a relief ship. Knowland confirms the three-hour window for rescue and offers a hopeful closing line: “Don’t lose your faith.” Faith and Towers exchange a quiet, relieved glance, their bond strengthened by the ordeal, signaling the end of the crisis and the endurance of the human spirit against the unknown perils of space.

Arrival back to Space Station X-7 and Dan's collapse
Maj. Gordon Towers and Capt. Dan Webber return to Space Station X-7 after collecting geological samples and ice from the Moon's caves. Dan collapses upon arrival and is rushed to the infirmary by Dr. Hoffman. Gordon is reunited with Faith Montaine, his girlfriend and a civilian biochemist aboard the station.
Dan's illness and the fungal clue
Hoffman struggles to diagnose Dan, ruling out space raptures because they cause hallucinations rather than a high fever. Faith notices a welt on Dan's leg that rapidly grows into a large fungus, suggesting the spores came from the Moon caves. Dan is placed in isolation to prevent spreading.
Cromwell's erratic command during the meteor approach
Col. Frank Cromwell, the station's commander, behaves oddly as a swarm of meteors closes in. He cannot issue evasive orders without prompting from Lt. Connie Engstrom, the communications officer. The moment hints that something is terribly wrong with his grip on command.
Dan dies and the denial of the fungus
Dan dies, his body horribly disfigured by the fungal infection. Cromwell inspects the corpse and dismisses it as nothing unusual, refusing to report the death to Gen. Knowland. He claims the death was due to 'pressure shock' and warns others to keep silent about the fungus to avoid panicking the crew.
Gordon's attempt to remove Cromwell leads to mutiny accusations
Gordon decides the situation warrants removing Cromwell from command, but Cromwell accuses him of mutiny. He orders Connie to relay a report to Knowland accusing Gordon of holding the crew at gunpoint. Connie secretly records the order, setting up later exposure.
Connie's transmission and the revealed fungus threat
Connie transmits the mutiny report to Knowland while also delivering news that the fungus is spreading through the station. Knowland suspects something is wrong because weapons had been outlawed for decades. The crew learns the entire station is under fungal threat.
Earth Control contemplates drastic measures
Knowland tries to reply to X-7 but there is no response, signaling a complete break in contact. He contemplates destroying the station to prevent the fungus from reaching Earth. He recognizes the gravity of the situation as the fungal threat spreads.
Hoffman falls ill but reveals a cold cure
Hoffman contracts the fungal infection and becomes gravely ill, yet manages to tell Faith and Gordon that the fungus can be killed by cold. This discovery becomes critical to the plan to retake control of the station. The illness heightens the urgency to counter the threat.
Second attempt and Cromwell's sabotage
Gordon, Faith, and Hoffman mount a second attempt to retake X-7 from Cromwell, who is now fully under space raptures and trying to destroy the station. Cromwell is confined to his quarters, escapes, and sabotages the communications system, cutting off all contact with Earth. He is recaptured later.
Cooling and exterior fungus mystery
The team discovers that lowering X-7's interior temperature below zero kills the fungus inside, but it begins to grow on the exterior surface due to unshielded solar heating. The mystery of exterior growth puzzles them until a staff officer suggests the sun's heat as the culprit. They begin adjusting their approach to manage the heat.
Knowland's ice-cloud plan
Knowland devises a plan to launch a rocket that will explode and form a cloud of ice crystals for X-7 to pass through, freezing the exterior fungus. The operation relies on manipulating orbital exposure to cold air and ice. The crew prepares to implement the solution to save the station.
Relief on the horizon and a hopeful ending
The plan succeeds and the exterior fungus is killed. Gordon uses the repaired communications system to request a relief ship, and Knowland confirms it will arrive in three hours. Faith and Gordon share a relieved smile, believing the crisis is finally over.
