Snowpiercer

In a post-apocalyptic future where climate engineering has failed to reverse global warming, humanity's last remnants cling to life on a perpetually motion train, the Snowpiercer. Seventeen years after a catastrophic attempt to stop the new ice age, the elite passengers in the extravagant front cars rule with an iron fist, while the poor and desperate are confined to squalid tail compartments. When the tail-section leader, Curtis Everett, leads a revolt against his oppressors, he discovers a dark secret about the train's true purpose and the sinister plans of its enigmatic creator, Wilford.
