It all begins when Ka-hee (Hwang Ji-hyeon), an emotionally and psychologically damaged woman, finds a spirit medium to help her address her troubles. Her inability to give birth to a child had long tortured her, and now she will do anything to cheat that fate.
She ends up burying an orphan in a large traditional pot used to burry kimchi underground during the winter and killing him. What she gains for this merciless act is a child of her own. Ka-hee eventually gives birth to a son she names Bin, but Ka-hee soon meets a brutal death.
The film continues as Bin's aunt Sunny (Han Eun-jeong) and her husband Jang-hwan (Park Seong-min) come to live with the now orphaned Bin in his home, which is haunted and where the pot still is. Bin also starts to reveal his violent side.
