Harbouring 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 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.
