The Golden Time Team continues to meet crime head-on. They respond to a subway bomb threat, but team leader Kyung-hak is yet to arrive on scene.

Convinced that her suspect did not act alone, Kwon-joo considers her next move, and how best to rein in the unpredictable detective Kang-woo.

A convicted child rapist is released from prison and strikes again, to the anguish of the victim's family. Detective Do chases an all-too-familiar suspect, but nothing remains in his grasp.

While in custody, a suspect dies of an apparent heart attack. Later, Kang-woo receives a message from the real mastermind.

Kang-woo and his team mobilize to rescue Park's wife from a kidnapper. But they clash with Chief Inspector Na's team, who are also hunting for the same man.

The Golden Time Team begins to investigate Chief Na, but when one member gets overzealous in his research, they unwittingly alert their target.

A popular vlogger swears he encountered a zombie which then goes on to attack other victims. Skeptical, the investigators search for the truth.

Chief Na tells Kwon-joo of his suspicions about Kang-woo, mentioning his mysterious past and bouts of amnesia. Eun-soo receives threats from an ex-boyfriend.

Amidst suspicion that Eun-soo may have perpetrated a stabbing, the team arrests her. However, they soon notice evidence of another armed perpetrator.

Detective Kang-woo is thrust into a high-stakes hunt with all of Poongsan's cops out for whoever's behind the disappearance of one of their own.

The serial killer reveals himself to Kwon-Joo and Kang-woo, but it only makes him lash out even more as he goes to teach the Golden Time Team a lesson.

Kang-woo can't help but think something's off when the serial killer brazenly turns himself in. Bang Je-soo explosively pushes Kang-woo to face his past.
