Tunna blå linjen

We meet some police officers in Malmö, their tiring everyday lives and the constant difficulties in keeping work and private life separate. Sara is an idealistic, Christian and newly graduated police officer. She is paired with Magnus, who is rock hard and cynical. Sara's gullibility is tested when she offers personal support to a young girl. Jesse and Leah are both experienced and ambitious but both have problems at home. They get something else to think about when they are sent out to look for a missing girl and an Afghan refugee boy.

Sara struggles with her protective instinct and not bringing her emotions to work. When she and her colleagues storm a brothel, she is again given responsibility for vulnerable people. Can she not get involved emotionally? Leah's grandfather Jurek is angry at everything and everyone around him. A new integration project in the neighborhood will be his new object of hatred. Jesse is an old fox but he feels he is starting to lose control. A horrible crime reminds him that he can not always supervise his eldest daughter.

Sara and Magnus like each other. It is quite clear. But as if overnight, the mood changes completely and Magnus becomes angry and irritated. Something is bothering him, but what? Jesse can not let go of his worries about his daughter Siri. His thoughts run away when he encounters her in town with new friends. Jurek's fight against Nami and his gang does not give Leah any peace. Now he demands that she let him take matters into his own hands.

The police's powerlessness in the face of the high crime rate disappoints Leah. When another murder of a young boy is put on the shelf, she can no longer just watch. She decides to raise her voice. Magnus and Sara pull in different directions in their approach to the job. They are given a shared responsibility over a helpless person, which puts even more pressure on their relationship. Things are made worse by the fact that Sara receives an unexpected visit. Leah has told Jurek to calm down and not get a weapon. He has not listened.

If there is one thing that never changes for a police officer, it is to always be treated with hatred and ingratitude. Not least for Leah, who constantly listens to her grandfather's complaints. Sara and Magnus' relationship, which is still stumbling, feels equally inconsolable. At the same time, Faye and Dani have moved in the shadows, almost as if they are hiding something. But after a tragedy in Stockholm, everything changes. Hatred of the police is transformed into love. Jurek goes from furious to sad. Magnus and Sara's unspoken feelings get a voice. Faye and Dani - during a desperate struggle to get a woman to leave her abused husband - come closer and closer to telling their secret. And general unrest in society turns into terror.

Magnus has let go of his cynicism and stubborn style. Now he instead gets the chance to help young people glide by training Nami and his gang in handball. The question is whether they will allow themselves to be controlled. Leah works harder than ever and things do not get better because Björn puts everything in her lap. She is under increasing pressure to make a change. Jesse tries not to be so worried about his daughter. But suddenly something happens that makes him fear for her life.

The heavy crime is frightening in Malmö. Innocents are often affected. At the same time, there is a hatred among some who are just waiting to get out. Sara has been thrown into this and has had to reconsider her idealism. She has already encountered violence, hatred and racism and the threat and responsibility are putting pressure on her. An innocent victim is the starting shot for a demonstration where all hatred is unleashed. Extremists are pitted against each other. The police are in the middle. And it looks like it's going to be violent.

After crime in Malmö has grown, the police have taken an increasingly tough line. The government is now introducing special visitation zones in vulnerable parts of the city. It gives strong reactions. Sara and Magnus have come so close to each other that there is no doubt about what they both want. Magnus has understood that, and starts planning a date with her. Unfortunately, there are others who like to put obstacles in the way of that idea. Jesse's family situation has gone downhill. Malin comes with more bad news.

Now all obstacles between Sara and Magnus have finally disappeared, and the first step is to plan a date. The only thing that stands in the way of their happiness now is themselves. Jesse is constantly worried about Siri's well-being and their relationship is tense. Everything is turned upside down when Jesse finds evidence that Siri is really slipping. The pressure from work and colleagues is only growing over Leah. But in any case, the situation has not felt life-threatening. To date.

In the end, Sara and Magnus have found each other. They are affectionate and wedge more firmly than ever. It seems. But when Sara is unexpectedly sent home to Umeå, she gets the chance to think about her future once again. Leah still can not give up her over-ambitious work discipline and now even her own body begins to protest. The atmosphere between Jesse and Siri is icy cold. As icy cold as the serial rape investigation after a DNA test released the previously suspected perpetrator. But a new event causes both the case and the relationship between Jesse and Siri to take an unexpected turn.
