"Set more than seven years after the world has become a frozen wasteland, Snowpiercer centers on the remnants of humanity, who inhabit a gigantic, perpetually-moving train that circles the globe," reads TNT's description of the show. "Class warfare, social injustice and the politics of survival play out in this riveting television adaptation."
