Train TO Busan
A chemical leak at a biotech plant causes the start of a zombie apocalypse that rapidly spreads across South Korea. Fund manager Seo Seok-woo is a cynical workaholic and divorced father. His daughter Su-an wants to spend her birthday with her mother Na-young in Busan. After being overcome with guilt after watching a video of Su-an suffering from stage fright while singing “Aloha ‘Oe” at a recital due to his absence, he decides to take her to Busan via an early KTX 101 from Seoul Station. Other passengers include working-class man Yoon Sang-hwa and his pregnant wife Seong-kyeong; selfish COO Yon-suk; a high school baseball team, including baseball player Min Yong-guk and team cheerleader Kim Jin-hee; elderly sisters In-gil and Jong-gil; and a homeless stowaway.
As the train departs, signs of chaos from the infection reach the station, and an infected woman runs inside, unnoticed, just before the doors close. She soon turns into a zombie, attacks an attendant, and many crew and passengers are quickly turned into zombies. The remaining passengers quickly secure themselves in the front and rear cars, observing that the infected zombies only attack if they can see them or hear them, but they can’t operate the train’s doors. They learn from news reports of the rapidly-spreading epidemic across the country, and Seok-woo discovers the biotech plant was connected to his business. He uses his connections to try to secure safe travels for Su-an and himself.
