Dark Hole

Um grupo de sobreviventes lutam por suas vidas contra mutantes que são criados quando humanos respiram uma misteriosa fumaça negra vinda de um buraco.

The news of the sinkhole spreads throughout Muji and more people come to look. However, things go wrong as they get infected by the black smoke and start attacking each other. Not knowing how it is triggered, but a large amount of smoke ascends from the hole and slowly covers Muji city. Hwa Sun and Tae Han go separate ways for their own objectives, but they both fight their way through the chaos.
