Park runs a small snack bar on the banks of the Seoul's Han River and lives with his two sons, one daughter and one granddaughter. The Parks seem to lead a quite ordinary and peaceful life, or maybe a tad bit poorer than the average Seoulite. Hee-bong's elder son Gang-du (by Song Gang-ho) is an immature and incompetent man in his 40s, whose wife left home long ago. Nam-il (by Park Hae-il) is the youngest son, an unemployed grumbler, and daughter Nam-joo (by Bae Du-na) is an archery medalist and member of the national team. One day, an unidentified mutant suddenly appears from the depths of the Han River and spreads panic and death, and Gang-du's daughter Hyun-seo is carried off by the monster and disappears. All the family members are in a great agony as they have lost someone dearest to them. But as they find out she is still alive, they resolve to save her.
