Zzongbie, the naive zombie confronts the greatest danger in his life after meeting PARK's family. Human Bio, the biggest pharmaceutical company in Korea conducts illegal experiments on humans. One day, a test goes wrong and results in the creation of a zombie. Soon, in the remote countryside, the oddball PARK family makes their acquaintance with the zombie in question, Hyun-woo. Rather than afraid of this strange creature, PARK’s family plots to make money out of him, especially after realizing the ’old’ father’s sudden restored virility from a bite of the zombie. Only the youngest daughter Hye-gul takes a liking to Hyun-woo, and nicknames him "Zzongbie, the pet". Will Zzongbie make a home with his ‘weirder than zombie’ family?
