Zembla is a Dutch television documentary programme by VARA and NPS. The documentaries are based on in-depth research which can take months. The subjects are often controversial. A documentary in 2001 about fraud in the Dutch construction sector led to parliamentary inquiries. In May 2006 the programme exposed the fact that politician Ayaan Hirsi Ali had lied in her claim for asylum, which led to her resignation from parliament.

In protected areas of the internet, a shadowy network is growing. Online chat groups where young people incite sadistic violence. Vulnerable children are being abused and mistreated, sometimes driven to suicide. Zembla shows that the network has also reached the Netherlands. But who is behind it?
