Rebellious Ki-soo from North Korea is mesmerized by tap dance in prison camps. Ki-soo joins as a team member of a dance team named ‘Swing Kids’. Yet suddenly, their dreams about dancing in prison camps are put in danger.

Former teen idol Nam Hyeon-soo is now in his thirties and working as a radio DJ. One day a young woman named Jeong-nam shows up and claims to be his own daughter. She also has a son whom she claims to be Hyeon-soo’s grandson. Their relation is proven via DNA tests by Hyeon-soo’s brother. This leads to Hyeon-soo attempting to avoid a scandal concerning him having children “unknown” to the media.
