After its surprise cancellation by TNT’s parent company WBD, Snowpiercer season 4 has finally settled into its new home on AMC. Based on the graphic novel series by Jacques Lob and Jean-Marc Rochette, which became a classic movie from Bong Joon-ho, the sci-fi show follows the remnants of humanity who inhabit a perpetually moving train in a world that has become a frozen wasteland. Class warfare rules the day in the 1001 cars as the characters battle their way to survival, prosperity, and hopefully warmth.
