Three prostitutes are found dead: one in Antwerp, one in Berlin, and one in Copenhagen; each had been shot through the left eye and had a finger cut off, and each had received a visit just hours earlier from Belgian journalist Jean-Louis Poquelin.

Lithuanian billionaire Marius Loukauskis is suspected of masterminding a criminal network specializing in human trafficking and forced labor; Loukauskis is at the top of Europol's most wanted list, but he has proved legally untouchable.

When the Danish police arrive at the chicken farm, the building is burning brightly and several of those forced to work there have died in the flames; the survivors leave the police in no doubt that this was modern slavery at its worst.

Loukauskis slipped away, but at least the team can put an international arrest warrant on him.

The more the team learn about Loukauskis' methods of putting trafficked people into forced labor, the more it becomes obvious how effective his organization works; he can just disappear in an instant, so they can't keep up with him.

Seven people are murdered during a brutal shootout at a B&B in Denmark's marshland. The only survivor of the massacre is the young Syrian woman Malu Barkiri, who escapes into the vast marshland area.
