Wolfs and Eva are called to the scene of a young man's brutally mutilated body. It soon becomes clear that some time ago, while driving far too fast, he caused a traffic accident in which a mother and child were killed. When a witness reports seeing the husband near the scene of the crime, it appears to be a revenge killing. Marion tries to mentor intern Joe, but that proves to be easier said than done.

An amber alert is issued and soon a witness reports an incident at a gas station. He says that a girl had asked to use his phone to make a call. It turns out that she had called the children's helpline to warn that a girl was about to be kidnapped. The Amber Alert is withdrawn when it turns out that the girl has run away from home. But Wolfs and Eva can't get the call to the children's helpline out of their minds. Especially when another call is made to the helpline and a young girl disappears. Joe and Marion are confronted with a mentally disturbed young woman. They offer help, but how can they actually help her?
