A new planet filled with solar system refugees sets the stage for the fourth season of "The Expanse," premiering today (Dec. 13) on Amazon Prime.
It has been a long and winding road (through space) for the crew of the Rocinante, the starring ship of "The Expanse." The show has also gone through a dramatic leap: This will be the futuristic interplanetary saga's first run on Amazon's streaming platform, after initially airing on the Syfy channel but getting canceled after the third season.
You can watch Season 4 of "The Expanse" for free with an Amazon Prime (opens in new tab) subscription, or you can sign up for a 30-day free trial (opens in new tab) to the service.

In essence, the show explores what the solar system might look like if people began living away from Earth. There's also an alien problem, and the way powerful figures weaponize this life-form, known as the "protomolecule," has played a key part in the story. As a trailer for Season 4 reveals, this alien "protomolecule" shows no signs of going away.
The new season follows Capt. James Holden (Steven Strait), asteroid belt "belter" Naomi Nagata (Dominique Tipper), Earthling Amos Burton (Wes Chatham) and Martian pilot Alex Kamal (Cas Anvar). The crew accepts a request from U.N. Secretary General Chrisjen Avasarala (Shohreh Aghdashloo) to check out the situation unfolding on "New Terra," the newly adopted home of several refugees who come from the asteroid belt. This world lies beyond a wormhole network called the "Ring," which played a big role last season.
If you want a refresher on the plot, Amazon Prime put together a video with the help of filmmaker Kevin Smith. Warning: There is some adult language in this video.
If the trailer is any indication, this new chapter will keep on delivering the goods on alien danger, space romance and Aghdashloo's captivating on-screen presence. The series shows no signs of slowing down: Amazon Prime already greenlighted a fifth season for the series.
Filming New Terra scenes means the show now boasts a brand-new location. The uncharted planet was shot on a frigid, barren landscape of a quarry outside of Toronto. But there will still be plenty of spaceship interiors for fans to enjoy, if the trailers are any indication of what's in store.
All four seasons of "The Expanse" are now available on Amazon Prime (opens in new tab).
