Snowpiercer(bc Sunday)

In 2014, to combat global warming, a chemical is released into the atmosphere, but with disastrous results. The world soon becomes completely covered in ice and snow. Now in the year 2031, life on Earth is barren except on the train Snowpiercer. The train has been circling the world perpetually for years. It has also separated passengers between the first class and coach. The first class passengers are wealthy patrons who paid for their expensive tickets when the train was first set to launch. Passengers in coach are free loaders who boarded the train out of sheer desperation. Life for the coach passengers are hellish and they finally decided to sets out to take over the engine room and free the people from the tyranny of the first class passengers.
