On an early spring morning, Septimus Akofeli, a newspaper delivery man of Somali origin, discovers a lifeless body in one of the apartments and automatically becomes the first suspect. A typical murder of an elderly alcoholic by a young immigrant - investigators initially conclude, but soon abandon this version. The new district police chief, Anna Holt, demands that the criminal be found and put behind bars as soon as possible. Among her subordinates there is only one knight capable of killing a dragon - the charming lazy man and sensualist Evert Bäckström. A sixth sense tells the astute commissioner that the matter is more complicated than it seems, and another murder cannot be avoided.
