Allegedly, despite already a grown-up, Soo-an will still be haunted by the harrowing experience she and her father had on that fateful day while they were aboard the train to Busan. As the zombies continue to plague humanity, Soo-an is said to be bent on finding a cure to the virus and will team up with other people, in order to save humanity from extinction.
