Three young immigrant boys, Wasim, Riaz and Munawar, come of age in the east end of Oslo, Norway. They find school boring and become attracted to the hard boiled gang East Side Crew, run by brothers Sadiq and Khalid. Petty theft soon develops into drug dealing, violence and murder.

The series is about police investigators in Greenland police and the assignments they receive. Every day they face new challenges that affect them differently. These consist of inspector Jan Erik Holm, Hassan Mohammed Arif Osman, Trond Olsen and Holms ex-wife Cecilie Melvold. The series paints a somewhat grim picture of Oslo, it is a place where no one is safe, where nobody is above threats and blackmail. Even policemen are subjected to harassment.
