To celebrate Naz's graduation from the Police Academy, her mother and uncle organize a dinner with the locals. During this dinner, a suspicious incident on the opposite sidewalk does not escape Naz's attention, and she immediately goes after the person she suspects. After a short chase, she catches the suspect, but there is a problem. The person she caught is none other than Commissioner Pamir, the indispensable name of the civil operations of the organized branch. After this unfortunate encounter, fate brings them together again in a covert operation aimed at the capture of Tarık Kosuoglu, a major arms smuggler. Moreover, as husband and wife. Naz and Pamir are now Tarık Koşuoğlu's new neighbors Yaz and Levent Güneş.

While Levent and Yaz are having dinner with Tarık and his family, Adem enters their house to find out who their neighbors are. He finds a weapon hidden among the books and tells the situation to his aunt's son Tarık. Tarik now suspects that his neighbors are the police. Adem thinks that Levent and Yaz will not be understood to have entered their house, but Levent realized that someone had entered their house thanks to the solution he had in mind before leaving the house. Now the attention of both parties is on the other. Tarık tries to keep Levent and Yaz close to them and sets a trap for them. While Levent and Yaz are trying to get rid of this trap, the information that Uncle Namık has security on the site confuses things.

Yaz and Levent come face-to-face with Uncle Namık when they think they are victorious against the Tarıks. While Namık's work on the site makes things increasingly difficult, Talat realizes that Tufan has a job he is trying to do in secret from his brother. While they plan to use this situation to pressure Tarık, they also try to get Namık to leave his job on the site. But a surprise development turns everything upside down when things are starting to turn right.

Caught by Namık, Levent and Yaz manage to get out of their difficult situation, but their jobs are getting harder and harder. Meanwhile, Tarık's illness and hospitalization completely changes the course of events. Levent and Yaz place a listening device in Tarık's room with the excuse of keeping an eye on Ömer in Tarık's absence. While everything is progressing as they wish, a surprising development occurs.

Levent and Yaz lie to Aynur to get out of the difficult situation they are in, but convincing Aynur will not be as easy as they think. Things get complicated when Aynur wants her only daughter to leave her house in a wedding dress. While all this is going on, Tarık and Adem notice the listening device that Levent has set up. It will not be easy for Yaz and Levent to get out of their difficult situation.

As Tarik is about to make his expected offer, the listening device they encounter in the room causes a stir. As Levent deftly banishes doubts about the bugging device, new questions arise in Tarik and Adem's minds about who put the bugging device. Meanwhile, Aynur continues to insist on her daughter's henna. He also insists on having the wedding. Sadullah learns what happened to the chief. While Tarık's expected delivery takes place, Yaz's absent-mindedness puts the operation in jeopardy.

Yaz kissing Levent starts a jealousy crisis. Levent tells Yaz that he is jealous of her and jeopardizes the operation. Yaz befriends Zeynep to prove that she is not jealous of Levent and to access more information. This friendship disturbs Nehir and makes it clear that she wants to get rid of Zeynep. Tarık and Adem play a game to better understand the Tufan’s intentions. Meanwhile, Aynur insists on holding the wedding of Naz and Levent. An unexpected person seen among the guests during the wedding turns things upside down.

While Naz and Pamir struggle to manage Zeynep, who unexpectedly appears at the wedding, Aynur reveals that Yaz is a police officer, and Zeynep suddenly disappears from the wedding. While she was going to tell her father about everything, she sees her suitcases in front of the door and learns that Nehir was kicked out of the house with their fillings, and gives up telling what she saw. Yaz and Levent thought that the operation was over and lost their hope when Zeynep got a surprise phone call and said that she would help them. On the one hand, unaware of everything, Tarık instructs Levent to carry out the delivery that will make the operation successful. While everything is going smoothly, Zeynep disappears again. The Kosuoglu family is caught red-handed and all the secrets are revealed. A butterfly flies into the air and this story ends with all the surprises it has given us.
