The Shims would be in the top five for being indifferent and apathetic for each other and in the top three for lack of love in a family. The five members of the family have absolutely no common ground. The family consists of the cheap, stubborn mom (Moon Hee Kyeong) and the father (Cheon Ho Jin) who is down because of her, their son Yong Tae (Yu Ah In) who thinks he was a king in his past life and their daughter Yong Sun (Hwang Bo Ra) to whom existence itself is a mystery, and the out of work comic book writer aunt (Kim Hye Su). Because they share the same blood, they all live awkwardly together in one house. And they wonder time and time again... why they have to live together when they don't even love each other.

One day, the Shims come face to face with calamity. Mom falls for a guy at the karaoke shop (Lee Ki Woo), Yong Sun meets a teacher (Park Hae Il) who is more of a mystery than she is, and Yong Tae falls in love with the worst girl (Jeong Yu Mi) in the universe. But most shocking is Mr. Shim, who is second to none at being cautious and straitlaced, and his most obscene incident! To make matters worst, Yong Gu, their playboy dog, gets a pure pedigree pup pregnant and the Shims fall in a calamity that could almost make one die from embarrassment.
