The Host (Gwoemul)

During the disposal of formaldehyde from a US military base, a huge amount of toxic substances are poured into the Han River. After some time, a terrible monster appears in the river.

There are many people who want to sit on the river bank in Seoul in the summer, and trade there is brisk. The owner of a stall with beer and snacks, Hi-bong, has two idiot sons and a smart daughter, a nationally known medalist in archery. And, of course, the old man, like the entire family, dotes on his only granddaughter Hyun-seo. It had to happen that one fine day the river monster came out to chase tourists along the bank and took Hyun-seo with him, and then, in front of the simpleton father’s eyes, swallowed the girl.
