Nima needs more samples for his experiments, so Milius sends Wilford and the soldiers to collect; privately, Milius tells Wolf tohug Wilford; Layton wakes up on an abandoned floor and is approached by humans with toxic gas scars.
Snowpiercer is set in 2021, seven years after the world becomes a frozen wasteland, 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.
