The film is based on National Singing Contest, an actual TV show that is the longest-running Sunday TV program in Korea since its premiere in 1980.

Popular TV program "National Singing Contest" is set to film in the city of Gimhae. Contestants in Gimhae hope to appear on the show for various reasons.

His life long dream though has always been to sing. One day, he sees a banner for TV show "National Singing Contest," which is set to hold auditions in Gimhae. Complicating things for Bong-Nam, his wife Mi-Ae (Ryoo Hyoun-Kyoung) is tired of Bong-Nam pursuing music. Mi-Ae is falling in debt and she wants Bong-Nam to get his hairdresser license so they can work together.
