Director Yeon Sang-ho's nerve-racking zombie movie, Train to Busan, broke South Korean box office records when it hit cinemas last week, and now it's made it Stateside.

The movie tells the story of a bunch of passengers in the first-class lounge of a bullet train on its way to the port city of Busan. The elite travelers soon find themselves facing a twitching, hissing and flesh-eating threat from the cheap seats. It transpires that there is an unidentified virus sweeping the country and the Korean government declares martial law. Those on the train must fight for their own survival.

Basically, it's a high-paced, high-adrenaline zombie movie set on public transportation with a side helping of class warfare. It stars Gong Yoo, Ma Dong-Seok and Jung Yu-Mi, and is showing at select theaters now. Watch the trailer above.
