Every day on the job is tense, dangerous and possibly lethal! But the dangerous situations are diffused without using force by the expert negotiator Joo Sung Chan, who leads the police department’s negotiation task force. The team handles the most dangerous, volatile and high-risk situations that jeopardize the lives of innocent people. Hostage crises, terrorist threats, and other major catastrophes await Sung Chan, Yeo Myung Ha and the other highly skilled team of negotiators when they come into work every day. Son Hee Sung is a thorn in their side as an aggressive broadcast journalist who tries to report on the many coverage-worthy events.
