Imagine a parent's worst nightmare. Someone takes your children and flees far away. Who do you put your trust in? And how do you get them back? In this episode of Insider, we follow an investigator in search of an ethnic Norwegian mother, who has abducted her two children on the run from child welfare.

Only a few years ago, a group of women were hidden on the floor above a pizzeria in the small town of Skarnes and sold on the streets of Oslo. For the first time, Insider has been given unique access to both the accused, the victim and the police. This episode tells a story about one of Norway's worst human trafficking cases.
