The Expanse - All Seasons

In Season 1, the disappearance of rich-girl-turned-political-activist Julie Mao linked the lives of Ceres' detective Joe Miller, accidental ship captain James Holden and U.N. politician Chrisjen Avasarala. Amidst political tension between Earth, Mars and the Asteroid Belt, these three individuals unravel the single greatest conspiracy of all time.

The Protomolecule has taken over Eros and threatens the safety of the entire solar system. From there, the larger conspiracy to control the protomolecule is further unraveled, as the crew of the Rocinante, UN Undersecretary Avasarala and Martian solider Bobbie Draper attempt to prevent system wide war AND stop a mysterious new creature.

As the Rocinante crew digs deeper into the search for Prax's missing daughter, the war between Earth and Mars turns deadly in ways the solar system has never seen. But a new threat in the outer reaches of the Belt could prove much more dangerous, threatening to test the very future of humanity.

With the Ring Gates now open to thousands of new planets, a blood-soaked gold rush begins, igniting new conflicts between Earth, Mars, and the Belt. Meanwhile, on one unexplored planet, the Rocinante crew gets caught in a violent clash between an Earth mining corporation and desperate Belter settlers as deadly new threats from the protomolecule emerge.

In different parts of the Solar System, the crew of the Rocinante and their allies confront the sins of their past, while Marco Inaros unleashes an attack that will alter the future of Earth, Mars, the Belt, and the worlds beyond the Ring.

The sixth and final season of The Expanse picks up with the solar system at war, as Marco Inaros and his Free Navy continue to launch devastating asteroid attacks on Earth and Mars. As the tensions of war and shared loss threaten to pull the crew of the Rocinante apart, Chrisjen Avasarala makes a bold move and sends former Martian Marine Bobbie Draper on a secret mission that could turn the tide of the conflict. Meanwhile, in the Belt, Drummer and what's left of her family are on the run after betraying Marco. And on a distant planet beyond the Rings, a new power begins to rise.
