Seong-il is up to a domiciliary visit to Ma Jin-seok, who has an insane amount of unpaid taxes.

Seong-hee, who thinks Baek and Yang are up to something, ends up reporting them to the police.

Detective Sa follows the steps of Jeong-doe and arrests Baek Seong-il and Squad 38.

Squad 38 has successfully made the tax evaders pay up their taxes, but they encounter more problems.

Squad 38 turns their target to Bang's son's company and the Bang's daughter, who collects antiques.

Ann becomes aware of Squad 38 and follows Baek's steps. There he ends up finding their hideout.

Squad 38 encounters a twist when Sa who still holds a grudge against Yang disturbs the mission.

Jeong-doe runs away with the tax obtained from Bang Pil-gyu and this leaves Seong-il in great shock.

Baek hears that the tax department is on the verge of disappearing because of the black business.

Caught in Choi's trap, Yang goes to prison, and Baek returns to the life before Squad 38.

Squad 38 gains more power with CEO Yang and plans to collect the insane amount of unpaid taxes.

There was a spy in the squad all along, and Choi Chul-woo has heard the master plan.
