Mi-ra, who runs a small snack food restaurant, has a trouble-maker brother, Hyung-chul. After being discharged from the military, he goes missing. After five years Hyung-chul suddenly comes back home accompanied by a middle-aged woman, Mu-sin. He gives a bunch of flowers to Mi-ra and introduces Mu-sin as his wife, even though they have not had a wedding ceremony. Mu-sin looks at least 20 years older than Hyung-chul. From that moment, an eccentric family is born.
