Newly graduated Sara from Umeå is trying to find her way in the Malmö police. She and her partner Magnus are called out when five-year-old Belle disappears from her mother.
The police storm a brothel, and Sara is given responsibility for vulnerable people. It awakens the protective instinct in her. Leah's grandfather Jurek is angry at everyone.
The mood changes abruptly between Sara and Magnus. Something is bothering him, but what? Jesse gets upset when he meets his daughter Siri with new friends.
Leah is disappointed with the powerlessness of the police. When another murder is dropped, she must say no. Sara and Magnus have different approaches to the job.
The growing crime rate leads to the police taking an increasing tough stance; when the government introduces special visitation zones in vulnerable parts of the city, the citizens react badly.
