Snowpiercer

In a frozen, post-apocalyptic world, the last remnants of humanity survive aboard a perpetually moving train, the Snowpiercer. This colossal train is a microcosm of society, rigidly divided by class, with the wealthy living in luxury at the front and the poor struggling in squalor at the tail. When a rebellion brews among the lower classes, the fragile social order threatens to shatter, forcing a desperate fight for survival and justice.
