In a snow-ravaged world, a group of travellers fight for survival on a train that perpetually circumnavigates the globe. The vehicle's occupants are divided into a military ruling elite and their dishevelled captives. But now, 17 years after the train set out on its seemingly never-ending journey, the downtrodden, abused captives have had enough. Revolution is afoot.
