Police investigator Magnus against all odds gets a big case, and is joined by his depressed colleague Dan and the neighboring kid Nikolai.

Magnus believes he sees a troll, but that's too much for police chief Arthur.

Police investigator Magnus, his partner Dan and neighbor Nikolai suddenly have enemies; but they can be used in the investigation.

Police investigator Magnus decides a great birthday celebration, kids style, is a smart diversion in case the killer shows up uninvited.

Magnus is quite lost after unintentionally causing a death, but Nikolai is rather inspired by the event and starts off on his own; Dan is tired of life.

Police investigators Magnus and Dan try to investigate from inside jail, but things aren't quite right; dead people live again; Arthur is back.
