In a near‑future where humanity teeters on the brink of annihilation, a colossal asteroid named Flora races toward Earth, casting a pall of dread over every orbiting outpost and ground‑based launchpad. The story unfolds largely aboard Gamma 3, a sleek but isolated space station that doubles as a launch platform and a micro‑cosm of the world’s fragile hope. The visual palette is cold and metallic, punctuated by the stark glare of solar panels and the endless black of deep space, while a low‑grade hum of machinery underscores a tone that sways between urgent dread and restrained optimism.

At the center of the operation is Jack Rankin, a seasoned commander whose calm authority masks a personal calculus of risk and responsibility. He is joined by his longtime colleague Vince Elliott, a fellow commander whose complicated past lends a subtle edge to their partnership, and Hans Halvorsen, a meticulous science officer whose curiosity about the unknown often pushes the limits of protocol. Their interactions blend professional respect with the strained camaraderie that only high‑stakes missions can forge, creating a layered dynamic that drives much of the film’s emotional core.

The crew’s objective is simple yet perilous: descend to Flora’s surface, plant a series of explosives, and obliterate the asteroid before it can strike. The operation is executed with surgical precision, but the aftermath brings an unexpected and unsettling complication—a viscous green slime clinging to a sample container, its alien texture hinting at properties far beyond ordinary space debris. The very act of returning to Gamma 3 with this mysterious substance introduces an undercurrent of unease that begins to seep into every corridor of the station.

As the station’s sealed environment tightens around its occupants, the presence of the slime transforms routine procedures into a tense dance of containment and discovery. The film leans into an atmosphere of claustrophobic suspense, where the crew’s ingenuity is constantly tested by an enigmatic, electricity‑siphoning entity that refuses to be fully understood. The interplay of scientific curiosity, military discipline, and the looming threat of an unseen contagion keeps the viewer hovering on the edge of anticipation, poised to see how far these individuals will go when the line between mission and survival blurs.
