After rocketing to fame as an off-handed serial killer in The Chaser, a cab driver pushed to extremes in The Yellow Sea, and one of Korea's coolest gangsters in Nameless Gangster, Ha Jung-woo finally gets the one-man movie he deserves. A disgraced TV news anchor demoted to drivetime radio call-in shows, Ha is a callow opportunist in career purgatory when a man phones in, blows up a bridge, and claims to have other bombs hidden around Seoul. Unfolding in real time, set mostly in the claustrophobic radio studio, the film is a showcase for Ha, who manipulates, bullies, cajoles, cowers, lies, and unleashes righteous anger as he goes up against an unseen terrorist, trying to save lives while also trying to resurrect his career. A master class in wringing out maximum suspense from one man and a microphone.
