About the series
The world has suffered a man-made catastrophe that triggered a new ice age. A giant train filled with survivors races along the trans-Eurasian railway. Aboard the train reigns a strict class hierarchy: from the ruling elite in the front carriages to the oppressed at the tail end. A smaller train has attached itself to the main one. Mr. Wilford (Sean Bean) intends to get rid of it, but Mel (Jennifer Connelly) and Layton (Daveed Diggs) use force and cunning to stop him.
