This action-comedy is the story of rookie IMF secret agent Yoo Da-hee on her first mission: gathering intelligence about the illegal smuggling of firearms into Korea.
Private Detective and former secret agent Woo Soo-han gets involved in the case but due to his inexperience and clumsiness, he fights over small issues with Da-hee. Things become complicated when their witnesses are murdered and the two of them are left prime suspects.
