The SnowPiercer

Snowpiercer is set in 2026, seven years after the world becomes a frozen wasteland due to ecocide, and follows the remnants of humanity who have taken shelter on a perpetually moving luxury train. Designed and built by the eccentric billionaire, Mr. Wilford, the train consists of 1,001 carriages and circles the globe 2.7 times per year. The constant motion of the train provides energy and prevents the passengers from freezing as well. Since the catastrophe, the train's population has become rigidly separated by class, caught up in a revolutionary struggle against the strictly imposed social hierarchy and unbalanced allocation of limited resources.
