Mr. Zombie (2010)

Original title: 미스터 좀비

Yeong-cheol is a totally incompetent man in his 40s. He runs a small chicken restaurant, but his fried chicken is the worst-tasting chicken in his village. He loses all his money, which is actually a paltry amount, in the stock market and leads a pathetic life. Worse, he gets bitten by a zombie and becomes one. One day, his family is plunged into a serious crisis because of the money that Yeong-cheol borrows from loan sharks. Yeong-cheol, who sees himself as totally powerless, fights them to save his family.
