Brothers and teenagers Luka and Vanja, grow up in Dorcol with a single mother. The younger brother, Vanja, is trying to establish himself on the sports field, while the older brother, Luka, is doing business. Luka goes to a house party and there he meets a girl, Danica, to whom he sells ecstasy. After the tragedy that happens at the party, Luka's life changes completely. He is in a gap between a powerful businessman and a third-class inspector who is trying to find him. Luka goes to the elderly criminal Boris, from whom he asks for help. Boris agrees, but asks Luke for a favour. At the same time, Inspector Gaga is trying to track down a sniper who entered the country and thus prevent the murder. These two stories intertwine and suggest a connection that will reveal much bigger secrets.

The investigation of the explosion that took place in the Hangar leads to a surprising realization that will be a trigger for revenge planning for some characters, while it will make others fight for their lives. Mirijana Tomić Sremica will not stop until she finds her brother's killers, Petra will have to explain to the inspectors why she came to the Hangar and why Rade only called her, while Gaga is working on her own again.

Police summon Petra for questioning. Inspectors Marta and Gaga are investigating the nature of her relationship with the mobster Rade Sremec, with whom she saw that evening when he was killed. Radet's sister, Sremica, is also looking for the killer. Luka manages to escape from the room where Boris kept him tied up and physically abused him. He wants to leave the country illegally, but he is soon persecuted by a man who works for Danica's father, a girl who was killed at a party where Luka was selling narcotics.

Police Inspector Gaga comes to the hotel again and tries to find out more from its owner, Strahinja, about why Strahinja was the target of a sniper. Fear, however, does not help him in that intention. Vanja traveled from Belgrade to the village of Amajlije, located in Bosnia and Herzegovina. He was followed by Boris, a criminal who had a hard time with Vanja running away from him. Petra's aunt is upset because she discovered the revolver that Petra was hiding in the apartment.

Boris came to Stanislav's parents and asked them for five thousand euros, which Stanislav allegedly owed him. His parents don't have that much money, so Stanislav's mother goes to the bank and brings the money to Boris. Vanja goes to Petra's. He asks her to take him to Sremica. Petra helped him and brought him to Sremica, who was ready to listen to him. Vanja told Sremica that she knew who killed her brother, Rade Sremac.

The police are trying to find Stanislav at the school, with the intention of getting as much information as possible about the drug dealer, Boris. However, Boris realizes that he is in danger from many sides. He comes to his mother who is aware of the danger that her son is in from doing business on the other side of the law. The mother is bitten by the conscience that she accepted money for her treatment from the controversial businessman Strahinja and thus put Boris in an envious position from Strahinja.

The police come to Petra's apartment to interrogate her. Petrina's aunt persuades her to tell the police all about the gun that Stanislav gave her for safekeeping. Inspector Gaga comes to Vanja's mother, Milena, who begs him to do everything in her power to help her protect her son. Police searched Stanislav's apartment with the intention of finding a gun. When they find a gun and several packages of marijuana in his apartment, they take Stanislav to the police station.

After three months in the correctional facility, Stanislav returned home. Petra tells Stanislav that she no longer has the will to continue the emotional connection with her. He indifferently accepts their breakup. Petri is now much closer to Vanja. Vanja, who entered the cryptocurrency business, cannot come to terms with the fact that his brother Luka is dead. The owner of the hotel, a controversial businessman, Strahinja, has returned to Belgrade. Police found out about it and installed wiretaps in his apartment.

Policewoman Jaksic comes to the prison to visit her boyfriend, who seriously stepped into criminal waters. The two are in a secret intimate relationship. Jaksic demands that he get in close contact with the prisoners who belong to the Borca clan. Jaksic's boyfriend is afraid of that clan because its members show extreme intolerance towards him. Vanja finds out that Petra's mother was in prison because she killed Petra's father. Petra tells Vanja that she no longer wants to hide drugs in her apartment.

Petra's mother, Lenka, warns Petra that she should not play with her future. Petra is young and intelligent and Lenka is afraid that her drug dealing can only take her to prison. Lenka spent a long time in prison for the murder and knows how hard life is in that place. However, Petra did not listen to her mother's warnings and is preparing for an even deeper entry into the dangerous dealer waters. For now, the politician has given up the action for the legalization of marijuana. Such an action requires a lot more money than is available to him. That giving up causes Strahinja's dissatisfaction.

Gaga and Marta, who work in the police, decided to buy an apartment on credit and thus continue living as a family, which would neutralize the turbulence they went through in previous years. Stanislav could no longer withstand the abuse that Kosta inflicted on him and retaliated by severely wounding him. Stanislav was taken to the police. They tell him that he can get out of that situation because it is a matter of self-defence, but they ask him to reveal to them who is dealing with Kosta.
