The drama portrays the reality of Korea through diverse insurance crimes that are prevalent in the country. There are the 'copy cats' that imitate and improve the existing crimes, and the 'mad dogs' who catch these bad cats.


Choi Kangwoo (cast. Yoo Ji Tae)

He was a police officer and later leader of an insurance investigation team at an insurance company. He has sharp eyes and good intuition, and he never lets go once he takes a bite. Even though insurance investigators don't have investigative authority, he boasted fraud detection rate of 99 percent while staying perfectly within the legal boundaries. But one day, he realizes that it is impossible to catch the most vicious insurance crooks while acting within the law, so he creates his own team, 'Mad Dog,' to investigate without holding back in using extralegal means. He no longer has any faith to keep.

Kim Minjun (cast. Woo Do Hwan)

No one would believe the fact that he used to be a runaway teen and a con man from his gracious looks and hearty laugh. He is as clever as a fox. He can make any face he wants and become anyone he wants, and nobody knows his real face. When he was seven years old, he was adopted by a German couple after he lost his parents in a car accident. When his adoptive parents gave birth to a son by artificial insemination, he became a child that no one desires. He was abandoned at the age of 17.

Jang Hari (Cast. Ryu Hwayoung)

She is a sexy, voluptuous and smart insurance investigator who was formerly a gymnast. She also used to work for Kangwoo in the insurance company and joined his team 'Mad Dog.' Her primary task is infiltrating in disguise, taking advantage of her gymnastic skills. In order to catch the bad guys, she transforms into any character, from an innocent university student to a bar girl in a skimpy dress.

Park Soonjung (cast. Jo Jae Yun)

He is an ex-thug with striking criminal records, and now he is an insurance investigator with a nursing license. He dreams of becoming a pediatric nurse for his love of children. Sadly, it will be hard for children to like this muscular, tough-looking man holding a syringe in his hand. He is in charge of various tasks related to medical records and field investigation in 'Mad Dog.'

On Nuri (Cast. Kim Hye Sung)

He quit high school and worked as an electronics vendor before joining 'Mad Dog.' He is a loner. Well, Steve Jobs is his one and only friend, only in his dreams. He is as pale as a ghost since he refuses to go outside unless he is covered in long sleeves and long trousers with his hat pulled down. He hates human. He likes machines because machines operate with no intentions unlike humans. With an incredibly high IQ, he is in charge of all the IT and machinery tasks in the team.
