One night, the kozjak Aljoša kills a priest of the Russian church who found him in the robbery of treasures hidden in the church walls. Young Inspector Stanko Pletikosic gets his first task - to solve this murder together with the inspector-inspector and veteran veteran Andrej Tanasijevic Tane. Stanko seizes Tane in the bar, and the beginning of their cooperation does not seem to be promising. People of Vrangel who are stationed in Belgrade, Colonel Sorokin and Captain Fjodor Fjodorovic, realize that Vrangel's relics have been stolen from the church, but they do not confess it to the police. At the insights of the church, Tane and Stanko seize the bloody message "greeting from Tatk". This message seduces Tanet and Stanko, as well as Vrangel's people, on a false track - Macedonian opium smugglers ...

In the late evening hours, Tane and Stanko meet again at the inspectorate - at the masquerade at the House of Commons. Wife of public prosecutor Vojin Djukic, Violeta, someone cut off his head. Tane notes that the victim and Maja Davidovic have identical costumes. He examines Maya and Vojina and quickly concludes that Maya is Vojin's mistress. But, Chief Dimitrijevic appears on the inspectorate and forbids Tane to further question Vojina and Maja.

Tane and Stanko found out in a photographic shop only that the heada killed Neven in order to take away photographs of the masquerade. Tane still worries more that Maya was on the spot again. She was suspicious, so she took her to the Hampshire where she examined her, and then shook her purse. Maja is scared that Tane found the negatives in his bag, but he cures when he is released and when he sees that the negatives are still there. However, Tane replaced the negative .....

After Aljosha is abducted and killed, Tane is furious with Dimitrijević and suspects that the prison doctor was paid to get him out of prison.

Tane, barely alive, finds Niški with her people and leads him to Prša. Tane learns from Niski that Krojač is a war veteran and that in the past he has been in contact with the famous Tankosić and his "black arm boys".

Maya was initially shocked that Avram was a butcher, but when he recalls some details, everything begins to get a new meaning.

Tane and Stanko examine the evidence against Živojin, who could have been involved in Avram's death.

A raid in Macedonia comes as retribution for Damjan's abduction. Stanko admits to Tane that he killed Stavre.

Tane finds Stanko in a bar. Tane tells him to go to Toponica and talk to Prince Djordje , the author of the painting "The Black Sun", which hangs on a wall in Avakumović's house.

The final clash is close. Tane and Stanko ask Dimitrijević to guarantee that Kaluđer will be brought to court if they arrest him.

The last days of 1933. After the failed attempt to assassinate King Alexander in Zagreb, it is clear that Yugoslavia is in a serious political crisis. Great political and strategic games are entangled both domestically and abroad, the very survival of Yugoslavia is called into question. However, Belgrade is shaken by something completely different; a gruesome murder on Avala, in the medieval fortress of Žrnov at the place where a monument to the unknown hero Ivan Meštrović will soon be built. Inspector Pletikosić, the current head of the Belgrade Department for Blood and Sexual Crimes, takes over the investigation, with the help of his young assistant Zečević.

After the arrest of the insane Rajko, an order comes from the highest institutions to stop the investigation of the murder in Žrnovo. Inspector Pletikosić, doubting this theory, asks for help from his friend and former boss, Inspector Tanasijević, who, having left the police, now leads a completely different life. As the disappearance of Novicki represents a serious problem for the state, Prince Pavle orders General Živković to find out as soon as possible what happened to the count. That disappearance also seriously disturbs Maja Davidović, who did not fulfill the task entrusted to her. Mustafa Golubić, protected in his shelter, slowly weaves a web in order to find out what kind of conspiracy is brewing. Everyone sticks to their own interests, alliances are established, but nothing is as it seems at first glance.

The killer's trail leads to the grave of the unknown hero and the secret of who is really buried there. But while investigating that clue, Stanko and Zečević, with the help of Tane, come across clues that spread the mystery even more. Meanwhile, in Italy, right on the border with Yugoslavia, a new "strong" man of the underworld is preparing to enter the scene. Tomasović rescues the Macedonian terrorist Damjan from his Ustasha friends yesterday, and through him he wants to establish the Yugoslav production and distribution of a new drug - heroin. Fortunately, Maja Davidović and Mustafa Golubić, although ideological enemies, decide to cooperate in discovering who is behind the plot to kill the king.

A huge scandal erupts with the discovery of Count Novicki's corpse. Maja asks Tane for help in the investigation that she is conducting herself. The plan to demolish Jatagan Mala and build a new settlement in its place is starting to be realized. Mirić receives instructions to cooperate with Godina, a mole in the Ustasha ranks, in the opium trade. Obrad Savković, the owner of the magazine "Novog doba", implements his agenda step by step using intrigues and blackmail. Maja gets more and more entangled in a story she doesn't fully understand. Tomasović approaches Mirić in order to agree on cooperation. Sonja, Tane's ex-wife, leaves her husband. And while it seems that new alliances have been made, in a moment everything changes, and the killer continues his bloody feast.

The year is 1938. While Europe dances on the edge of the abyss, a dangerous web is woven in Belgrade around the ratification of the Concordat. Count Ciano and Milan Stojadinović shape the fate of the Balkans, unaware that in eastern Serbia, at the foot of mystical Rtanj, a wrath is awakening that threatens to set the country on fire. Horrific events in an isolated monastery become weapons in the hands of powerful figures from the "Conspiracy," an organization led by Zlata Mirić and the mysterious Prizrenac, which announces the end of the old order. Amidst the turmoil, the Minh family, owners of the Rtanj mines, try to preserve their property and peace, but upcoming conspiracies pull them into the center of a conflict they cannot control. While secret societies and conspirators mobilize in Belgrade's corridors, Tane fights his own ghosts, waiting for the return of the only man he trusts - Stanko Pletikosić. Stanko is released from prison into a world he no longer recognizes.

Belgrade is shaken by the news of the death of Julius Minh, the owner of the mines on Rtanj. Although the scene in hotel "Moskva" suggests suicide, Tane and young Čeda Diklić suspect that the hanging is only a bloody performance. Lavrentiy Beria sends Mustafa Golubić on his most dangerous mission yet—a return to Belgrade. In a world where no one trusts anyone, even within the Party, Mustafa must track down a mysterious group of conspirators supported by foreign powers. At the same time, in Paris, Josip Broz Tito awaits news from Moscow regarding his appointment as General Secretary of the KPJ and meets Maja Davidović. The recently released Stanko Pletikosić joins the investigation, almost against his will, realizing that in the four years of his absence the city has changed, but the atrocities have remained the same.

While debts to Danilo Tomasović are paid in blood in the port of Rijeka, Belgrade becomes the scene of a brutal struggle for supremacy. Stanko Pletikosić, in search of answers and through cooperation with Krojač, arrives at discoveries that will change the power dynamics in the Belgrade underworld. After the death of the man suspected of murdering Julius Minh, Tane and Čeda's investigation hits a wall. At the same time, in the relationship between Zlata Mirić and Mustafa Golubić, passion and espionage intertwine in a dangerous dance, while Mustafa slowly gains the trust of the conspirators. Tane, haunted by visions and exhausted by the investigation, seeks help from Vanuca, who takes him to the edge between reality and nightmare, where he will have to face the images from the past that haunt him.

Stanko's investigation leads to the discovery that "Rtanj cheese" is only a front for the distribution of a drug that changes the rules of the game in the Belgrade underworld. Stanko must use all his shrewdness to outsmart his enemies, as well as Tomasović, in order to find out who is behind the new goods on the market, while slowly taking over Krojač's place in Jatagan Mala. Tane finds himself in a state of complete breakdown. While visions from the Rtanj tunnels mix with images of political chaos in Belgrade, he realizes that the appearance of new heroin and the mystical ore from the mine are part of the same dark puzzle. On the edge of madness, Tane tries to warn Stanko that the enemy is not only on the street but also in what they cannot see.

Tane, devastated by a new murder, goes with Čeda in search of Dido de Mayo. Marija Oršić arrives in Belgrade, interested in the Minh mine, when we also discover who the new leader of the Belgrade Thule is. Tito tries to find out why Maja Davidović helped him, while Mustafa Golubić further complicates the situation of Prime Minister Stojadinović with an assassination. Although Tomasović is slowly losing patience while trying to understand who is behind the new heroin smuggling operation, Stanko is slowly connecting things and—with Kiro's release from prison—decides on new steps.

Tane wakes up in the hospital; Stanko offers him help to find the people responsible for the murders, as well as for what happened to Čeda. However, after the incident with Simeon, Tane finds out in Glavnjača that his hands are tied and that he will have to solve the case outside the law. With Stanko's help, on the street, Tane arrives at answers he could not reach through a police investigation. Mustafa meets with a foreign agent in Bulgaria, after which the direction of "The Conspiracy" changes abruptly. Tito, after learning what is in the Minh mine, comes to Belgrade and takes steps together with Maja Davidović so that the mine does not fall into the wrong hands; however, he loses Bojana's trust.

After the murder of a high-ranking government official, Prizrenac continues to scheme in order to succeed in hiding the secret about the mine from all interested parties, but fails to prevent Maja Davidović from taking an important step toward purchasing the mine. Tane tries to find out from Madam who she made the forgeries for, and then makes a deal with Stanko that could completely change the situation, both in the political leadership and on the street. Bojana is torn between Tito and Mustafa, although she is slowly losing the trust of both. While Tomasović's paranoia grows after the murder in the club, Stanko decides on a dangerous double game.

A large fire in Jatagan Mala further complicates the situation on the street, and Tomasović makes even more enemies for himself with ruthless actions. Stanko manages to win the favor of Simeon Draškić on Rtanj. Tane forms an alliance with Mustafa in order to uncover Prizrenac and prevent the sale of the Minh mine. Tane arranges a meeting between Maja Davidović and Mustafa Golubić, while Marija Oršić and the Thule are getting closer to achieving their goals, as pressure on Prime Minister Stojadinović grows.

Faced with a great loss, Tane discovers who Prizrenac is and comes one step away from proving it. However, after Madam makes a great sacrifice for her son, Tane and Stanko realize that the fate of the mine, the street, and ultimately all of Yugoslavia, will have to be resolved through a major conflict on the street. All actors, willingly or unwillingly, will have to face each other, after which the truth will finally come to light, and the future of Yugoslavia will be decided.
