Lucy Nekrasova’s sister, Masha, is going to leave for Moscow - she was offered a place in a respectable bank. Lucy is restless: in a dream the night before she saw her sister killed at a construction site. Masha safely settles in a new place, she is happy, but Lucy does not leave a foreboding of trouble. At night, Lucy breaks down in the capital, where she finds out that in the morning her sister did not appear at work. Police major Aleksey Potapov listens carefully to Lyusya, because she gives details of the murder - a construction site, something green ... Potapov politely sends out a “crazy” person with strange visions. A few days later, at the construction site in Zeleniy Lane, they find the body of a shot woman ...

Potapov is surprised at the details of the crime predicted by Lucy, but he is too rational to recognize Lucy’s ability to “see” what is hidden from ordinary people. Lucy is eager to help find Masha’s killer, but Potapov urges him not to interfere with the investigation and sends her off. Nevertheless, intuition tells the experienced opera that it’s worth trying to put together the pieces of the chaotic Lucin’s tips puzzle together. Lucy, meanwhile, begins an independent investigation ...

After the arrest of her sister’s killer, Lucy returns to her hometown. Meanwhile, in Moscow, the little granddaughter of the head of the department, in which Potapov serves, is kidnapped. All the police are on their feet, but there are no clues. The boss in desperation orders to bring Lucy to the cause. Potapov is in a quiet rage: he, an experienced detective, is imposed on a madwoman who does not understand anything in operational work. The investigation has two working versions, but Lucy insists that the police are on a false track ....

Lucy is learning to control her unusual gift, her visions are becoming clearer. But for Potapov they are all as messy as before. He openly taunts her, and the head of the department no longer believes in the girl’s superpowers. Potapov manages to get on the trail of the kidnappers ... However, Lucy is one step ahead, and it is this step that helps to avoid tragedy. Finally, Potapov has to admit that Lucy, despite all her oddities, can prove very useful in investigating complex cases. Lucy is offered to become a police officer ...

In the area there are several similar in style to the robberies of women. The criminal works quickly, the victims do not even have time to see him. The last attack ends with the murder ... Lucy has the first working day in the police. The girl is determined to help solve serious crimes, but Major Potapov is not ready to put up with a fortuneteller in the department, and the criminalist Marina, with whom Potapov is planning a wedding, begins to see a rival in Luce. Police detain a woman’s killer. No one but Lucy doubts his guilt ...

Potapov is forced to admit that Lucy was right in the innocence of the alleged killer: the evidence base against him crumbles before our eyes. However, another side is revealed in the gift of Lucy - she begins to see the tragedies that await outsiders and realizes that she is not able to prevent them. Lucy is very worried and wants to become “normal again, like everyone else”. She even decides to quit her job in the police. Only Potapov is no longer ready to let her go ...

At a corporate party in a boarding house, a young woman is strangled. The alleged killer is found dead in a nearby pond, and a bag with a large batch of drugs is found in the victim’s room. The interrogation of witnesses is delayed until late in the evening, and Potapov leaves the bag with prohibited substances in the safe of his office at the police station. The jealous husband becomes the next suspect, but Lucy feels that this is a false trail. She sees a person with two faces, but cannot explain what this means. Opera chuckle at the "witch." Potapov takes the side of Lucy and invites her to use her gift to put the jokers in their place.

Thanks to Lucin's gift, it is possible to find a thread to the killer. In parallel with the investigation of the double murder, Potapov is looking for facts that can help him find out the circumstances of the death of his father, a police officer, in the 1990s. My father dealt with the corruption case in the Ministry of Internal Affairs, and Potapov suggests that his murder was not accidental. The head of the department advises Potapov to stop "tedding the past." It soon turns out that in the bag that Potapov took from the scene of the crime, instead of drugs there is ordinary chalk. Potapov, who became the main suspect in the substitution of drugs, is arrested ...

The body of a shot man was found on the embankment. Lucy claims that the case is somehow involved ... fascists. But this time no one laughs at her, too often her unusual “strings” helped the investigation. This happens this time too. It turns out that the murder was committed with a pistol from the Second World War, traces lead to black diggers .... Meanwhile, the arrested Potapov faces a prison sentence: the keys to the safe where the drugs were kept were always with him, and there were no traces of breaking into the lock . So who made the substitution !? Suspicion falls on one of the operas, but Lucy claims that he is not guilty.

Done a new murder with a Walter pistol. Both victims had previously been implicated in the rape of the girl. The killer’s identikit completely coincides with the description of the victim, and her DNA was found at the crime scene. Lucy “sees” how this girl killed her victims, but she feels another person in her body. In addition, the suspect has an undeniable alibi. Thanks to Luce, Major Potapov is removed from all charges of drug substitution, but he understands that this story is just a warning, and if he digs further, the problems will become more serious and irreversible.

The apartment is brutally hacked down by a famous collector of antique weapons. The tool of crime, the most valuable samurai sword with a long history, also mysteriously disappears. The doors are closed by bolts, on the windows there are safe frames by special order, there are no signs of hacking ... How then did the killer get into the apartment and get out of it !? Modern ninja? Mystic? Luce comes with a vision of a burning house. This does not give any clue until it turns out that the missing samurai sword that killed the collector ... burned out many years ago in a fire.

Lucy claims that the collector’s killer entered through a safe window, which, however, cannot be opened from the outside. And the apartment is too high. Soon, the first suspect appears in the case: the former lover of the wife of the murdered one - a circus performer, an air gymnast, a parkour, whose abilities go far beyond the boundaries of an ordinary person. Moreover, he desperately needs money, and the young widow will get a huge inheritance and freedom of action. However, every day there are more and more suspects, and everyone has a motive.

In the park, a girl was found dead from a blow to the head. Suspicion falls on the ex-boyfriend of the deceased, but Lucy claims that several people are to blame for her death. Potapov and forensic scientist Marina are in full swing preparing for the upcoming wedding, and Lucy finally agrees to go on a date with Max in love with her. However, not everything is so cloudless: Potapov begins to feel pressure from the service of his own security, someone from the higher circles clearly does not want him to rush the old case about the death of his father.

The case of the girl who died in the park is even more complicated than originally thought. Lyusya and Potapov, using different methods, but complementing each other, build a chain of tragic circumstances. Maxim, who is in love with Lucy, invites the girl to fly with him to Paris. Lucy helps Potapov choose a suit for the upcoming wedding with Marina. In the meantime, the hunch is confirmed that Potapov’s pressure began at the “signal from above”. However, it is still not clear who this high-ranking customer is. An attempt is made on Potapov!

After the attempt on Potapov, Lucy, fearing for Alexei’s life, insists that Potapov should involve her in the investigation of his father’s death. Her help is invaluable, and finally gives Potapov a clue, as well as an understanding that everything is not so simple in his relationship with Lucy. Within a few hours, three accomplices involved in corruption are killed. The investigation has no doubt that the crimes are related, but Lucy insists that they are all random. One could listen to her this time too, if it hadn’t been found out that her best friends, including Max.

Suspended from police service, Lucy begins her own investigation, helping operatives to follow the criminals. Lyusya returns to work, only she is not ready to forgive Potapova of his suspicions against her. Although ... perhaps this is banal jealousy on the eve of the wedding of Potapov and Marina? Lucy agrees to fly with Max to Paris ...
