Harboring a traumatic experience that led him to avoid crime scenes, prosecutor Noh Jin-pyeong begins his first day of work in the city of Seowon.

While tracking down their immediate suspect, Je-mun's men find an unexpected link between Jo Yeong-guk, their ultimate target, and the city's mayor.

To find proof that Jo Yeong-guk committed bribery, Je-mun hatches out a plan that'll make it easier to locate where his dirty money is stored.

Jin-pyeong, who's full of doubts after a secret meeting with deputy chief prosecutor Ban Jun-hyeok, is tasked with interrogating a key witness.

Despite the chief prosecutor's instructions, Je-mun orders a stop to the search and seizure, and tries to pursue a new route to catch the bad guys.

When his team suffers casualties, Je-mun no longer has room for mercy and calls for Jo Yeong-guk's arrest -- no matter what it may cost.

The day of the final hearing arrives, and Je-mun prepares to conclude Jo Yeong-guk's case, but an even worse enemy threatens to thwart his plan.

Hoping to find answers regarding his late colleague's case, Jin-pyeong accepts Ban Jun-hyeok's offer and joins a special investigations team.

To pay his sister's hospital bills, Gang-ju has no choice but to get help from a loan shark, who offers to cancel the debt in exchange for a "service."

Heo Il-hu searches for the missing high school girl. Je-mun secretly investigates the cases that Special Team Three supposedly solved already.

Soon after Lee Myeong-deuk warns him to disband Special Team Three, Ban Jun-hyeok receives news that there's a problem within the team.

Detective Hwang from Special Team Three is in crunch time to catch the wanted men. Likewise, Je-mun's men prepare to take on their adversaries.

Not happy with how things turned out for Jo Yeong-guk, Je-mun tries to get Ha Sang-mo's testimony himself, but a shocking truth awaits.

Je-mun quickly closes in on Jo Yeong-guk. Meanwhile, Mayor Bae Sang-do's sister plans to do whatever she can to get her brother re-elected.

Mayor Bae's niece devises a foolproof political scheme for her uncle. Je-mun vows to get revenge -- for his comrades, and for all the people of Seowon.
