Kang Dong-seok (Lee Seo-jin) overcame poverty and left his small town to become a successful prosecutor.
A genius with an aloof kind of charisma, his arrogance and ill temper puts him at odds with many people, including his estranged family. After 15 years, Dong-seok is transferred back to his hometown and reconnects with his roots, re-learning the value of neighborly warmth in the countryside and the true meaning of love and family. His misfit siblings include Dong-seok(Ok Taec-yeon), his younger brother who works for a money-lending business; his older brother Dong-seok(Ryu Seung-soo), an events emcee who dreams of becoming an actor; and his twin sister Dong-seok(Kim Ji-ho), who is developmentally challenged and remained in a childlike state ever since an accident during their childhood.
There, Dong-seok happens to meet his first love Hea-won (Kim Hee-sun) and falls in love with her all over again.
