Tae-suk is homeless and lives like a phantom. His daily routine involves temporarily staying in houses and apartments he knows to be vacant. He never steals from nor damages his unknowing hosts' homes; rather, he is like a kind ghost, sleeping in other people's beds, eating a little food out of strangers' refrigerators and repaying their unintended hospitality by doing the laundry or making small repairs. Sun-hwa was once a beautiful model, but she has become withered living under the shadow of her abusive husband, who keeps her imprisoned in their affluent, expensively decorated house. Tae-suk and Sun-hwa are bound by fate to cross paths though their invisible existences. They meet when Tae-suk breaks into Sun-hwa's house and they instantly recognize the similarity of their souls. As if bound by unseen ties, they find themselves unable to separate and quietly accept their bizarre new destiny.
