In 2015, an experiment to counteract global warming causes an ice age that kills nearly all life on Earth. The only survivors are the inhabitants of the Snowpiercer, a massive train, powered by a perpetual motion engine
, that travels on a globe-spanning track. A class system is installed, with the elites inhabiting the front of the train and poor inhabiting the tail.
It's been 20 years since CW-17 was sprayed into the atmosphere to control global warming. 20 years since the ice age began. Wilford, the engineer of the train has died, allowing his son to rise to power. In celebration, he selects a young tail-dweller-he does this to show a new day has dawned. A day of hope for those in the back, of equality.
Once she's whisked to the front, the horrified girl discovers Wilfords son has no plans on improving her peoples lives. Oh no, she's alone now and vulnerable. No one cares what he does to her up here. She's completely in his power and if she complains or tries to escape....Well, he can shut off food and water to the tail section.
