Plot Synopsis

Based on James S.A. Corey's book series collectively known as "The Expanse," this thriller, set 200 years in the future, follows the case of a missing young woman who brings hardened detective Josephus Miller and rogue ship captain Jim Holden together in a race across the solar system to expose the greatest conspiracy in human history. By this point, humans have colonized the solar system. The U.N. controls Earth, but Mars is an independent military power. The planets rely on the resources of the Asteroid Belt, where air and water are more precious than gold. For decades, tensions have been rising between these three places. Now, Earth, Mars and the Belt are on the brink of war when a young woman goes missing. Miller, a native of the Ceres Station in the Asteroid Belt, is a detective for a corporate security force operating as the law in the Belt, and he discovers a newfound sense of purpose when he's put in charge of the investigation into a missing heiress. Holden, the 2nd officer on the ice-carrying freighter the Canterbury, is a natural leader who's not sure he wants responsibility, but who will soon have no choice when he is drawn into a dangerous plot. Meanwhile, on Earth, Chrisjen Avasarala has achieved one of the highest ranks in UN government without ever standing for election. She belongs to a longstanding political dynasty on Earth, dating back to the early days of planetary exploration and colonization. Martian separatists assassinated her father during a period of social unrest, and her son, a Marine, died in the line of duty while defending Earth from Belter revolutionaries. The Canterbury crew includes: chief engineer Dominique, a former Belter whose complicated relationship with violence and her troubled history have lead to an unlikely friendship with the Canterbury's mechanic, Amos Burton; pilot Alex, who grew up in Mars' Mariner Valley and enlisted in the Martian Congressional Republic Navy before signing up for this gig, which gives him the chance to visit the farthest reaches of the solar system; mechanic Amos, an Earther who doesn't talk about his past -- but knows a lot about brothels and Baltimore; and med-tech Shed, who has to operate at a dining table in the galley after the medical bay was removed when the Canterbury was gutted to clear the way for cargo.

Humanity has been given access to thousands of Earth-like planets, which has created a blood-soaked land rush that furthered tensions and ignited new conflicts between the opposing nations of Earth, Mars and the Belt. Ilus is the first of these planets, one rich with natural resources but also marked by the ruins of a long dead alien civilization. While Earthers, Martians and Belters maneuver to colonize Ilus and its natural resources, these early explorers don't understand this new world and are unaware of the larger dangers that await them. 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.

Amos returns to Earth to confront his past and the legacy of the life he fought to leave behind. Naomi reaches out to her estranged son in a desperate bid to save him from his father's toxic influence.
