"Shark" Lee Jung Gil begins to make his moves on Kim Nam Gil.

June 25, the 10th episode of the KBS drama "Shark" featured Jo Sang Gook (Lee Jung Gil) trying to frame Kim Joon (Han Yi Soo/Kim Nam Gil) for murder.

Detective Oh (Jo Jae Wan) begins to investigate the murder case of Jung Man Cheul (Kim Min Sang) when he finds a photo at the victim's house. The photo is black and white and appears to have been taken around the Japan's colonial period in Korea. On the back of the photograph, there is a date and Jo Sang Gook's (Lee Jung Gil) name.

Detective Oh goes to the library for more information on the photograph. He learns that the person next to Jo Sang Gook is someone who is part of the independence movement.

Suddenly, somebody appears in front of Detective Oh. The mysterious man is the person who murdered Han Young Man (Jung In Gi) and Kang Hee Soo (Choi Duk Moon) after receiving orders. The man kidnaps Detective Oh and asks him if anybody else saw the photo.

Meanwhile, Jo Sang Gook holds a party for the 44th Anniversary of Gaya Hotel. At the party, Kim Joon receives a photo on his phone. The photo is showing the corpse of Detective Oh. The body resembles the body of Jung Man Cheul when he was killed.

Kim Joon becomes extremely shocked at stares at jo Sang Gook, thinking that he is the one responsible.
