3 factions. Earth, Mars, and the Asteroid Belt (or Belters). Season 1 starts out with some discovery of some unknown molecule. Protomolocule I think is what they called it. A detective gets commissioned to find a girl who is missing and as he tries to find her he comes across this molecule. It turns out to be much more than anyone thought and it all goes to **** real quick.
Super well done science fiction. Good politics between the 3 factions; good characters and intrigue, and a really good plot.
The only actor I don't like is the old lady politician who's voice sounds like she smokes 3 packs a day.
