Only a few months have passed since Detective Max and his wife Asha lost their son. Their lives come to a standstill when Max transfers to a new job in Oslo in homicide. Max teams up with detective Sander, who knows the underworld of Oslo and has no illusions. Where Max is an ethical detective, but perhaps also a bit naive, Sander is tough and bitter, and a tad racist. The two clash immediately. The men are tasked with investigating the mysterious deaths of four young immigrant boys. There are no signs of violence or drugs, but there is evidence of a crime.
