For me, one of the most frightening apocalypse type events is bio warfare or a bio-accident. Disease that is hard to control coupled with it potentially having no cure or one that can’t be developed fast enough is just horrid to even think about. Train to Busan is not only an amazing horror/thriller zombie movie, but also one that portrays humanity in a time where it is survival of the fittest.
In the movie, Seok Woo is a fund manager who has a young daughter and is divorced from his wife due to him being a workaholic. In the beginning he is portrayed as a dad who is too busy with his job to spend quality time with his daughter. His daughter ends up guilt-tripping him into sending her back to her mother in Busan, a day earlier than she was supposed to go for her birthday. Fortunately, they catch the train to Busan where they just manage to avoid the imminent bio-apocalypse that is to befall the city of Seoul.
On the train, they meet Sang-hwa and his pregnant wife Seong-kyeong, a high school baseball team, rich but selfish CEO Yon-suk, elderly sisters In-gil and Jon-gil, and a homeless man. Just before the train departs, another wounded woman jumps into the train as well. She seems to have a wound on her leg that is infecting the rest of her body fast.
Meanwhile, Seok Woo has fallen asleep on the train, while his daughter wanders the rest of the compartments out of curiosity and the need to use the bathroom. Soon, the wounded woman succumbs to the bite and starts to seize. A stewardess comes to check on her and in the process becomes the first victim to the now zombified woman. The bite and turning is fast and relentless as one person becomes affected after another. The compartments are small and there is no where to run.
Passengers start to panic, and soon only one compartment of the train is left with no zombies in it. Hope seemed to be in the near future as the passengers are asked to get off at another city that is fortified by military. However, by the time they get there, the military has already lost to the city of zombies and have turned themselves. Their numbers are halved even more as they must run back to the train as soon as possible. Unfortunately, in the chaos, not everyone boarded the safe compartment. Our main characters are hiding in different ones and must battle through the zombie infested compartments to save their loved ones and make it to the safe head compartment. It becomes a long arduous process that shows the different sides of humanity. Every action becomes a choice of saving yourself or help for the good of a group.
