When the hater dies, the hatred may endure, and torrents of rage may engulf the earth. Tyson and Lana are on a summer break in Seoul. They link up with Sam and Steve, and the cheerful reunion of college friends turns into a wild, out-of-control night out. Lana and Tyson try the Korean spirit soju, and Sam tries his luck with Mimi, a spirited Korean. However, Steve is in a dismal mood and disappears into the night. The morning after is a sobering wake-up. Gangshi rise from the dead and take to the streets of Seoul—with Steve among them. Mimi, Sam, Lana, and Tyson vie to escape the city alive and in one piece—with their humanity intact.
