Just before Do-Ki lays the smack-down on Baek's goons. He confirms his plan with Ha-Na and tells her that every action has a consequence; he's well aware that this could backfire but he's willing to walk through fire.
Do-Ki immediately gets to work, knocking out General Manager Lee and demanding answers. A call from Goo sheds some light though, who mentions where the girls may be held.
Meanwhile, Go-Eun awakens to find herself with Maria, stuck before Jung-Geon and Choi Min with their camera. Kyung-koo is with Chairman Baek, and they're taking his fingers off one by one. Do-Ki is irate when he learns this, and after threatening Lee with a wrench, finds out they're being kept in storage.
This storage area sees Sung-Chool make a big sacrifice to save Kyung-Koo. Unfortunately it also sees him go blind in one eye as a result.
Meanwhile, Do-Ki shows up to save the girls, sporting steel knuckles. Go-Eun is a mess, especially when she's forced to watch her sister's video again. Do-Ki is not messing about though and he thwarts the threat, shooting Choi-Min in the groin with a nail gun several times. After repeatedly hitting him in the face, Do-Ki recovers the phone and symbolically has Go-Eun stamp it into obscurity.
As Go-Eun and Do-Ki drive off together, Jin-Eon looks to meet them. Unfortunately he's suddenly struck by the white truck of doom, driven by Joo-Chan. He plunges a knife into Do-Ki's neck before driving off. Jin-Eon passes away, leaving Do-Ki and Go-Eun grief-stricken and enraged.
Do-Ki drives after Joo-Chan, using the deluxe taxi's auto-drive to jump out at the last minute and flip the truck. The chairman is down, blanketed in a mosaic of broken glass and sticky blood. Do-Ki breathes heavily. He's thwarted the threat but there's still more work to be done. Do-Ki knows this and heads off to save Sung-Chool and Kyung-Koo.
He shows up with steel knuckles and prepares to work. Do-Ki takes out all the goons with a single, well-choreographed action sequence before confronting Baek and the others. Do-Ki manages to trick Baek, holding her up at knife-point and slicing a line across her face. In her fear-stricken state, Do-Ki convinces Baek to give the order and let Sung-Chool and Jin-Eon go.
While Baek manages to get away, Suk-Tae is left behind to deal with Do-Ki. He knocks him down until Do-Ki is surrounded by thugs. Too many to fight this time. Ha-Na shows up with a gun though, followed by a whole series of other officers.
In the ensuing chaos, Do-Ki manages to grab a police car and takes off. It turns out he has a tracker planted in Baek's truck, and Do-Ki listens to everything she says. Ha-Na figures out what Do-Ki is up to and follows in her own car.
With Baek out of time – and room on the dock – Do-Ki knocks the Chairman down as Ha-Na shows up to put handcuffs on her. Do-Ki admits he has faith in Ha-Na rather than the police force and begins walking away. As he does, the events of the episode catch up to him and he collapses on the floor.
