Korean horror directed by Sang-ho Yeon. The film follows Seok-woo (Yoo Gong), a divorced city trader who is taking his young daughter Su-an (Soo-an Kim) to stay with her mother in Busan for her birthday. However, following the sudden outbreak of a deadly virus throughout the country, the carriage of their high-speed train is overrun by a swarm of frenzied zombies. With the train hurtling towards its destination, Seok-woo and Su-an must team up with fellow survivors in a desperate bid to survive the journey.

Korean director Kim Jin-Woon pays homage to the master of the spaghetti western, Sergio Leone, with this action-packed adventure film set in 1930s Japanese-occupied Manchuria. A trio of Korean outlaws (played by Kang-Ho Son, Byung-Hun Lee, and Woo-Sun Jung) battle with the Japanese army and various Chinese and Russian bandits, bounty hunters and train robbers to gain control of the lawless territory.
