Wavve's original movie "Gentleman" is a light-hearted crime entertainment film about Ji Hyun-soo (played by Joo Ji-hoon), the president of a criminal investigation agency, who is involved in a huge incident while clearing his name. The film tells a tense story of Ji Hyun-soo (played by Joo Ji-hoon) working with Jin Hwa-jin (played by Choi Seong-eun) to personally find the victim in order to clear his name within a week. Park Sung-woong will play the role of Kwon Do-hoon (sound), the representative of a law firm who was born as an aristocratic prosecutor in "Gentleman", and show a strong presence.
