A young girl falls from an apartment building. Accident, murder, or suicide? Marion, who knows the girl from the street, thinks it's murder. Wolfs thinks it was suicide; the girl was addicted to drugs. Romeo is on a leadership course. Eventually, Marion and Wolfs unravel the events, but whether they have solved the case is questionable. The suspect they arrest is immediately deported to Belgium.

On his way back from soccer practice, a boy is sexually abused and murdered. He has a sports sock in his throat, reminiscent of an earlier case in Drenthe. When it turns out that the victim's coach in Drenthe—who was also a suspect at the time—now lives in Maastricht, all the alarm bells go off. Marion and Romeo encounter an elderly woman who is desperately lashing out at people in a supermarket. Is she simply demented and unmanageable, or is there more to her behavior?
