The South Korean National Intelligence Service is the equivalent of the American CIA. It is an elite division of the country where only the best agents serve. Once, Park Chang-mi (Choi Kang-hee), Lim Eun-yeong (Yoo In-young), and Hwang Mi-sun (Kim Ji-young) were considered among the best in their field, but they have since stepped away from this dangerous work. Suddenly, a new important mission arises. Park must infiltrate one of South Korea's largest companies, where intellectual property theft has occurred. Due to recent coordination issues, Lim is forced to become Park's partner instead of a possible promotion. Hwang leaves behind her home and household duties to become the third member of this close-knit team. This amusing action film is about female spies. Miscasting (Good Casting) stars Choi Yeong-hoon ("Obstetricians and Gynecologists," "High Society," and "Five Fingers").
