The Shameless () is a 2015 South Korean neo-noir crime drama film starring Jeon Do-yeon and Kim Nam-gil. It is written and directed by Oh Seung-uk, who described it as a "hardboiled romantic noir thriller.
The Shameless made its world premiere in the Un Certain Regard section of the 2015 Cannes Film Festival.
The police are staking out Park Joon-gil for the murder of Hwang Choong-nam, and jaded detective Jung Jae-gon is being pressured to close the case, particularly by his former superior Moon Ki-beom, who lost his badge for corruption. Joon-gil was once the mob enforcer for Jay Investment, but had fallen out of favor when he embezzled and stole the heart of Kim Hye-kyung, the girlfriend of the company's vice president Park Jong-ho. Jay Investment representative Min Young-ki approaches Jae-gon and offers him to ensure that Joon-gil is maimed during the arrest as payback. Jae-gon reluctantly agrees, but a botched arrest sends Joon-gil on the run, and Jae-gon decides the best way to find him again is by sticking with Hye-kyung, hoping she will lead him to the fugitive. Hye-kyung now works as a bar hostess to pay off her substantial debt to Jong-ho, and Jae-gon threatens his way into an undercover job as a floor manager at the nightclub she works at. Introducing himself as Joon-gil's former cellmate Lee Young-joon, Jae-gon begins to spend time with the suspicious Hye-kyung and gradually wins her trust. But when Joon-gil returns asking Hye-kyung for money for a potential deal, Jae-gon's newfound feelings of love and jealousy rise to the surface.
