To celebrate the revival of the drama 'Chief Inspector', Choi Bool-am and the four detectives from 'Chief Inspector 1958' - Lee Je-hoon, Lee Dong-hwi, Choi Woo-sung, and Yoon Hyun-soo - reunited for a talk show called 'Chief Inspector's Gathering'. 'Chief Inspector's Gathering' was originally a meeting started by the actors who felt sad when the original 'Chief Inspector' ended, to soothe that regret. As time passed, and colleagues who were together in the series passed away one by one, it became difficult to continue. Now, through this talk show, 'Chief Inspector's Gathering' has been reopened to reminisce about the past 'Chief Inspector' and celebrate the beginning of 'Chief Inspector 1958'.
