Read the complete plot breakdown of Project Gemini (2022), including all key story events, major twists, and the ending explained in detail. Discover what really happened—and what it all means.
In a not-too-distant future, a plant-killing virus is wiping out vegetation and driving Earth’s oxygen down to 18%, pushing humanity toward suffocation. Yet a fringe of scientists uncovers an ancient machine called the Sphere, a relic they believe seeded life on Earth, and a warp-drive technology built by the same civilization. A multinational team launches Project Gemini to carry a copy of the Sphere to a terraforming planet. On the voyage, a critical warp-drive hiccup forces them to abort the mission early and set down near a young world with a thin, unstable atmosphere, where the air is breathable only with external oxygen masks. Steve, Egor Koreshkov, leads the crew through the crisis, but the ship’s pilot defies orders to inspect the engine and is found dead outside the hull. The captain suspends Steve, and the crew accelerates their schedule to press the descent.
In a quiet flashback, Steve reveals a personal motive: he gifts his girlfriend Amy, Alyona Konstantinova, a bracelet crafted from a sliver of the Sphere. The moment hints at a longing to safeguard a future beyond the present danger, a theme that threads through every choice the crew makes. On the planetary surface, they deposit the Sphere into a cave and activate it, hoping to seed a sustainable habitat. Instead, the Sphere unleashes a Trojan—a bio-robot alien that quietly tests the boundaries of the lander’s airspace and security. The threat forces a reckoning: Steve and another crew member slip away to investigate the Sphere’s chamber, ignoring an order from the captain.
A brutal encounter follows. The Trojan attacks and infects the crew member, and Steve realizes a startling truth: their journey has not been through ordinary space, but through time. Four billion years of Earth’s past unfold before them, landing the crew on a primordial world long before life itself began. The breathtaking revelation reframes everything they thought they understood about their mission and their purpose.
Back in the present, the captain reveals a startling piece of evidence: a video showing that Steve had long suspected an anomaly within the Sphere—the very feature that birthed the Trojan. In the grainy footage, Steve appears alongside human-shaped holograms, suggesting a history of interaction with entities beyond their own era. The revelation deepens the mystery but also sets a path forward, as the crew pieces together a way to confront the threat across two timelines.
With the Trojan threatening not just the lander but Earth’s entire future, Steve studies the infected crew member’s blood and uncovers a critical clue: a vaccine formula hidden within the Sphere fragment. He engraves a portion of the Sphere onto the bracelet he once gave Amy, encoding the vaccine’s design in a personal keepsake that bridges their fates across time. Realizing the only way to contain the threat is to destroy the Trojan at its source, Steve makes a hard, painful decision to blow up the lander, sacrificing the ship to save the world.
The timeline threads tighten as Amy returns to the bracelet and decodes the hidden vaccine formula. She activates the first Sphere, initiating a new wave of discovery and possibility. In this moment, she encounters a human-shaped hologram—Steve from the past—an echo of the man who laid the groundwork for sacrifice and science. The exchange carries both farewell and guidance, with Steve entrusting Amy with the instructions needed to manufacture a lasting cure. As the two timelines converge, Amy’s resolve hardens, and she prepares to enact the protection that could secure humanity’s survival.
In the end, Steve’s decision to remove his oxygen mask and stay integrated with the Sphere’s machinations proves humanity’s last, best hope. The event horizon closes on a world saved from the brink, not by conquest or power, but by tenacity, memory, and the unyielding belief that knowledge—and love—can outlast even the most existential threats. The Sphere remains a gateway between ages, a reminder that progress often threads through peril, and that the courage to act in the moment can illuminate a future where life endures.
