The third season of The Expanse accelerates the overarching narrative, picking up immediately after the shocking bombardment of Earth. The system is on the brink of all-out war. On Earth, UN Deputy Undersecretary Chrisjen Avasarala and Martian Marine Bobbie Draper forge an unlikely alliance, racing to uncover a conspiracy that suggests rogue elements within Mars and Earth secretly collaborated to weaponize the protomolecule.
Meanwhile, the crew of the Rocinante—Holden, Naomi, Amos, and Alex—are trapped in the middle. They take possession of the hybrid child, Prax’s daughter Mei, and the protomolecule sample, making them a target for every faction. After a tense standoff, they barely escape to the legendary asteroid-belt settlement of Tycho Station.
The season’s first half culminates in a desperate battle near Jupiter’s moon Io, where the rogue Earth corporation, Protogen, is mass-producing hybrid soldiers. The Roci crew, alongside a united front of Earth, Mars, and Belt forces, assaults the facility to stop the program. The conflict seemingly ends with the destruction of the hybrids and a fragile ceasefire declared between the planets.
This peace is short-lived. A colossal, mysterious ring structure, built by the protomolecule, suddenly appears beyond the orbit of Uranus. This Ring Gate is a stable wormhole leading to thousands of habitable worlds. All human factions immediately dispatch ships to claim this new frontier, triggering a dangerous traffic jam of politics and military power in the confined space around the Ring.
The second half of the season shifts to this slow zone. When a Belter ship, the Behemoth (formerly the Nauvoo), attempts a high-speed transit through the Ring, an unknown, non-biological intelligence governing the space perceives it as a threat. It enforces a speed limit, causing catastrophic damage to every ship inside. Survivors from the Martian, Earth, and Belter fleets are now stranded together in a deadly standoff.
Inside this pressurized environment, tensions explode. Holden becomes a conduit for the Ring’s intelligence, experiencing terrifying visions. Different factions, led by the Behemoth’s first officer, Drummer, and a militant Belter named Ashford, clash over whether to fight or surrender to the unknown power. The climax sees the Roci crew and their allies risking everything to prevent a catastrophic attack on the Ring entity, which would have destroyed all the ships. They succeed by surrendering, demonstrating they are not a threat.
The season concludes with a profound new status quo. The Ring Gate is open, offering humanity an unimaginable expanse of new worlds. The Behemoth is renamed the Medina Station and becomes the first permanent settlement inside the Ring, a toll gate and watchtower for the new frontier. As colonists stream through to claim planets, a final, haunting shot reveals the protomolecule’s ancient builders were not the only force in the universe—something killed them, and it may still be out there.
