When Han Suk-Hoon was little, he was adopted by a family in the United States. He returns to Korea as an adult and works as an excellent surgeon, but he falls into a bottomless pit. He succeeds as a dumpling master.

In a comedic blend of mayhem and domesticity, Yoon Tae Soo takes up not one, but two high-stakes roles: head of the house and gangster kingpin. As the hardworking breadwinner of his family, Tae Soo may seem like just another loving father who’s trying to get by, but when he says he’ll stop at nothing to ensure his family’s happiness and security, he really means it.

Tae Ho and Sang Goo are two men who constantly fought at work and hates each other even more now that they’re both the heads of rival companies. When their children Do Hee and Young Joon get married, the bickering fathers are forced to become in-laws.
