This week on "Running Man," Uhm Jung Hwa and Kim Sang Kyung join the members as chief detectives and form two teams. The members of the Betrayer Club, Seok Jin, Haha, and Kwang Soo, want to break away from the detectives and open the treasure box. Meanwhile, the rest of the cast members try to get their composite sketches to arrest them as detectives. All the teams are desperate to win, and the race can't get any more exciting than this!
