Seoul hedge fund manager Seok-Woo (Gong Yoo) grudgingly took his estranged daughter Soo-An (Su-An Kim) aboard the high-speed KTX for a swift trip to his ex-wife’s. The journey wouldn’t be as smooth as advertised, however, as a zombie plague-infected teenager snuck aboard… and even those in first class find themselves trapped in a rolling slaughterhouse. Satire-edged shockfest.
