When Wolfs and Eva hear that a man has disappeared from a village near Maastricht, they quickly link it to a cold case investigation. Years ago, a child was raped and murdered in that village. They are now trying to solve that case with a DNA test on all male residents. What does the man's disappearance have to do with that case? Marion and Romeo are dealing with an escalating neighbor dispute. Sophia Arletti, an Italian detective, shows up at the station. She wants Wolfs to assist her with an investigation.

Eva is furious at Wolfs and Mechels and calls herself sick. But the case comes to her when David Boesmeer senses danger. He has been warned and all the mafia members have disappeared from the radar. Only Eva still has a clue as to where the mafiosi are. But will she share it with the team she is so angry with?
