Two hundreds years from now, Earth has colonized THE EXPANSE between us and the sun. Now, galactic peace is administered by the U.N., and humans live mainly in three areas: Earth, Mars, and the asteroid belt between Mars and Jupiter. Water and air are more precious than diamonds or gold, and it's during an ice-harvesting run when James Holden (Steven Strait), captain of ice freighter Canterbury, is involved in an incident that causes nearly its entire crew to be wiped out. Meanwhile, on the asteroid Ceres, Detective Miller (Thomas Jane) is given an assignment to find Julie Andromeda Mao (Florence Faivre), the daughter of a wealthy asteroid belt CEO, who's gone missing and is feared kidnapped; and on Earth, U.N. official Chrisjen Avasarala (Shohreh Aghdashloo) is investigating radicals on Mars. What the three don't know yet is that Mao's disappearance is connected to a conspiracy that doesn't only threaten life on Earth but will have consequences for every human life in the galaxy.
