This is a story about a swindler who is forced to share the body of a justice-loving detective in the Violent Crimes Unit. This drama depicts an interesting collaboration between two ill-matched individuals who work together to fight for justice. Cha Dong Tak is a detective who has lost his colleague. While trying to catch the killer, he runs into Gong Soo Chang, a conman who makes a living by picking pockets. While fighting, Soo Chang's spirit enters Dong Tak's. During this time, Dong Tak has no power over his own body whatsoever and doesn't remember anything either. On top of this, a cheeky, female reporter, Song Ji An, joins them on their investigation to solve crimes. As individuals, the three of them may lack in many ways, but as one, they are the most invincible and hilarious heroes there can be.
