What Season 4 of The Expanse

Season four sends the crew of the Roci to Ilus, a world much like Earth. With thousands of planets like it within reach, the scramble for resources has driven up tensions between Earth, Mars and the Belt. The first explorers who arrive on Ilus don’t understand the place or the dangers ahead. Holden and Naomi face challenges on that mission, while Bobbie tries to adjust to her life as a civilian on Mars. In the Belt, Drummer and Ashford fight piracy. Avasarala, UN Deputy Undersecretary, tries to keep the clash between Earth and Mars from becoming all-out war.
