A gym-obsessed serial killer murders and eats a local drug dealer for his protein, inadvertently sparking a brutal and bloodthirsty tit-for-tat turf war between rival drug gangs.

One idle summer night, three poor housemates, Jae-ho, Kyeong-soon, and Hong-chan order fried chicken with the money from the shattered piggy bank. When the food arrives, it is delivered by a large swine. A giant chicken soon follows, begging the 3 housemates that his fried chick is not to be eaten.
