Chief Yu is happy to see that unit one is complete. However, superintendent Choi suddenly appears, to give them an almost impossible mission, to arrest all the bums/beggars in Jongnam market. Yeong han advises the others to put toothpaste under their noses which they learnt later was to prevent smelling the body odors of the beggars. They go to the market and round them up, warning them not to steal again or cause chaos. Hojeong and Gyeong Hwan think they should be arrested per Superintendent Choi’s orders. However, Yeong han and Sang sun let them go. While they are at the old lady’s restaurant, Yeong han tells the others that the reason he caught so many cow thieves was because of the beggars who helped supply him with Intel.
They had all learnt that Hojeong was kicked out by his parents so they ask him where he’s staying at the moment and he replies his mother had secretly rented out a place for him. He also tells them the reason why he wanted to become a police officer, showing them a sheriff badge. He was inspired by Frank Hamer, the man who caught Bonnie and Clyde, the serial killer couple who was infamously known for armed robbery and murder. While Yeong han is having a nice time with the boys, he forgets that Hyeju is waiting for him at the movie theater so they can have a date. It isn’t until he and his boys are leaving that he hears a merchant advertising his movie, that he remembers and rushes away.
But it’s already too late. Hyeju waited till night before she left. Unable to face her, he lingers outside her book store listening to her vent her frustration about him to her friend Namin. But a newspaper boy catches his attention. He buys a paper from him and after reading its content, he learns that a group of robbers have been targeting several banks in different towns. They had even shot several security men to death during their operations. At the boarding house, his landlady reads the news paper along with other boarders. She figures that Seol would soon be their next target and asks Yeong han what he would do if that were to happen. He replies cheekily that he would catch them.
However, he’s very serious about the matter and the next day, discusses the situation with Chief Yu and the others. Hojeong knows they are former soldiers and figures they will be coming to Seoul. they wonder how he’s so knowledgeable about their operations and he responds he has been following them since their first attack. Superintendent Choi summons an emergency meeting announcing that all police officers would be protecting lee Jung jae during a meeting at Jongnam hall with Lee Hwaryong. Chief Yu and his team tell him about the potential of the armed ex soldiers robbing a bank in Seoul but Superintendent Choi and the other police officers don’t take them seriously. He even orders the other officers to report unit 1 to him if they disobey his instructions.
Meanwhile, the robbers are listening to their activities on the radio and are getting themselves ready to attack one of the banks.Yeong han and the team start investigating discreetly. Yeong han gets his suit and meets Hyeju at her book store to apologize. Hyeju looks impressed by his handsome looks but she’s still hurt he didn’t attend their date and stubbornly refuses to forgive him until Yeong han insists on helping her fix a broken shelf. During the process, she notices a cut on his wrist but doesn’t talk about it. After fixing the shelf, they sit down for tea and Yeong han gives the impression that he would like to come over again which makes Hyeju happy that she eventually forgives him.
They both take a stroll that night and talk about their interests. After some encouragement from Yeong han, Hyeju reveals she wanted to be an actress but her mother had threatened to send her to the convent if she insisted on it. She then asks Yeong han about the scar on his wrist and he reveals he got it when he was a student soldier. This surprises Hyeju. She suddenly buys a bracelet for him and wraps it around his wrist, telling him to always keep it with him. Yeong Han, moved by her kindness, promises to never take it off.
Meanwhile, the leader of the armed men decides to rob Goryeo bank. Yeong han and the team also figure out that Goryeo bank is their next target. They have a secret meeting in his boarding house and enlists the help of his banker neighbor to figure out the operation of the bank. They also enlists the help of the beggars who helped them identify when the armed men arrived at the bank to scope out the place. Hojeong spends days and nights trying to figure out when the armed men would attack. Sang sun who failed at rock and scissors has to act as a guard at the bank. He follows Yeong han to the bank to tell the branch manager there of the armed men’s attempt to rob his bank, lying that Superintendent Choi told them to protect the bank undercover.
Meanwhile, Hojeong, who hadn’t taken a bath in days, meets the group after his investigation and they are appalled by his stink. Ignoring their discomfort, he tells them that the armed men usually attack during an important occasion when the police are involved in something else. Now, the police would be protecting Lee Jung jae at the meeting with Lee Hwaryong leaving the banks defenseless. The meeting would be taking place at 11: am which is when the armed men would attack.
The next day, Sang Sun disguises himself as a security man and stays at the bank waiting. Unfortunately, Chief Byun and his men prevent Yeong han and the others from leaving. They get them locked up in prison and leave but they are able to reach into the emotions of the officer watching over them, officer Kim. Feeling saddened for the poor people who would lose their homes should this unfortunate attack take place, he decides to free them, even offering to escort them but upon arrival, it’s already late. The armed robbers have begun their attack and unfortunately, Hyeju happened to be there.
Thankfully, the branch manager is unconscious after Yeong han’s bank friend gives him a drink that had sleeping medicine in it. The bank robbers struggle to wake him up so he can open the safe but it’s to no avail so they decide to take the cash at the counter but then they hear the noise of siren and car honking. They hurry out but are intercepted by Hojeong and Gyeong Hwan. However, the armed men take Hyeju hostage so they are unable to shoot at them. The armed men escape in their car unaware that their driver is Yeong han. Gyeong Hwan had knocked out their member who was keeping watch in the car leaving Yeon han to disguise as him. He wears a mask so they are unable to tell who he is but Hyeju did immediately she saw the bracelet she gave him on his wrist.
His team members pursue the car and a shoot out occurs. However, it isn’t long before the armed men notice something is wrong because their driver is heading the wrong way. Highly suspicious, the leader threatens to shoot him if he doesn’t remove his mask. To save him, Hyeju acts like a crazy woman distracting them. But they eventually remove Yeong han’s mask but it’s too late for them. They are almost near the police station and a huge fight takes place. They get into an accident but Yeong han protects Hyeju from getting injured. Sang Sun and the others arrive and arrest the leader and the others.
Meanwhile, Superintendent Choi, Chief Byun and the other officers are in front of the station. They are surprised with what they see and join unit 1 to arrest the criminals. Hyeju insists she’s fine to Yeong han and tells him she was only acting to be crazy and he is very impressed. She tells him she wants nothing but to have something sweet with him. His teammates notice how close they are and ask if they are a team. Yeong han responds that he has a crush on her leading everyone to coo except for Hojeong who is shocked.
Superintendent Choi takes credit for what happened and decides not to punish Unit 1 because of the reward he secretly received. Yeong Han nearly forgets his date with Hyeju. When he arrives, she’s surprisingly still waiting for him. She understands this is what entails if she dates him. Yeong han takes her hand and the two enter the movie theater together.
In the next scene, we see a group of soldiers discovering something in the mountain. The episode ends with a strange woman whose face we can’t see having a call with an anonymous man asking her about a child that was supposed to be delivered to him. The woman responds that the child has already been placed in another good home.
